Are You Wasting Half Your Study Time Without Realizing It?
Hosni Showike • 27 September 2025
Here's how to make the best out of each study session (expert tips)
Research shows most students waste hours studying ineffectively. A 2013 study in Psychological Science in the Public Interest found that popular techniques like re-reading and highlighting are among the least effective ways to learn [1].
Let's fix that.
The Problem: Your Brain Forgets Fast
The "forgetting curve," discovered by Hermann Ebbinghaus in 1885, shows we forget about 70% of what we learn within 24 hours if we don't review it [2]. This means if you're just reading your notes once, most of that information disappears quickly.
Two Proven Solutions That Work
Research from cognitive science points to two main techniques that actually work:
- Active Recall: Testing yourself instead of just re-reading
- Spaced Repetition: Reviewing information at specific intervals
A 2013 meta-analysis of 217 studies found that practice testing (active recall) produced the largest effects on learning compared to other techniques [1].
How to Study Better: Simple Steps
1. Use Flashcards Correctly
- Make simple cards with one fact per card
- Test yourself regularly
- Apps like Anki use spaced repetition algorithms to schedule reviews [3]
2. Try the "Blurting" Technique
- Write everything you remember about a topic without looking at notes
- Check what you missed
- Fix your mistakes
- A 2011 study showed students who tested themselves remembered 50% more information a week later compared to students who just studied [4].
3. Practice Real Questions
- Use past exams or question banks
- Time yourself
- Review mistakes immediately
Research shows that practicing with real test questions improves scores more than just studying notes [5].
4. Track What You Study
- Keep a log of topics you've studied
- Note when you last reviewed each topic
- Schedule reviews based on how well you remember
Passive vs. Active Study Methods
Reading notes is a passive method where you simply look at information. Studies show this leads to poor retention—only about 20% after one week. An example is reading through a textbook chapter without engaging with the material. While it feels productive, your brain isn't forming strong memory connections.
Highlighting text is another passive approach where you mark important points in your notes or books. Like reading, it also results in poor retention (about 20% after one week). Many students highlight entire paragraphs, which doesn't force your brain to decide what's truly important.
In contrast, active recall is a method where you test yourself from memory. This approach leads to excellent retention—about 80% after one week. Using flashcards is a perfect example, as they force you to retrieve information rather than just recognize it. This strengthens memory pathways in your brain.
Spaced repetition involves reviewing information at increasing intervals over time. This active approach also results in excellent retention (around 80% after one week). Scheduling reviews just before you're likely to forget information helps move knowledge into long-term memory efficiently.
According to data from Dunlosky et al. (2013), the difference between passive and active methods is dramatic—a four-fold increase in retention after just one week [1].
7-Day Plan to Fix Your Study Habits
Day 1: Set Up
- Pick your 3 hardest topics
- Create 10 flashcards for each topic
- Download a spaced repetition app like Anki (free) [3]
Day 2-3: Start Active Recall
- 20 minutes: Review flashcards
- 20 minutes: Practice "blurting" on Topic 1
- 20 minutes: Answer 5 practice questions
Day 4-5: Build the Habit
- 20 minutes: Review due flashcards
- 20 minutes: Practice "blurting" on Topic 2
- 20 minutes: Answer 5 more practice questions
Day 6-7: Test Your Knowledge
- 30 minutes: Review all due flashcards
- 30 minutes: Mixed practice questions
- 15 minutes: Plan next week's topics
Common Mistakes to Avoid
- Mistake: Making flashcards too complex
- Fix: One fact per card
- Mistake: Cramming the night before
- Fix: Study a little each day (research shows this wo
- rks better) [6]
- Mistake: Not sleeping enough
- Fix: Get 7-9 hours (sleep helps move information to long-term memory) [7]
The Bottom Line
If you're not using active recall and spaced repetition, you're likely wasting at least half your study time. By making these simple changes, you can learn more in less time.

IGCSE and IAL Guide for 2025 - 2026 Exams
Bottom line IGCSE is moderately challenging for ages 14–16 and prepares students for A-Levels or IB. Difficulty varies by subject, exam board, and tier. This guide cites published comparisons and exam-board-aligned facts to help you choose and prepare. What Makes IGCSE Hard (or Not) Position in the system IGCSE is a foundation stage that builds core concepts before deeper post-16 study. Evidence shows it leads into A-Levels or IB and is widely recognised: IGCSE builds fundamentals and is more exam-led, preparing students for the higher analytical demands of AS/A-Levels. IGCSE is equivalent in rigor and recognition to GCSE and accepted by universities and employers worldwide. IB includes deeper content and heavier internal assessments than IGCSE, confirming IGCSE’s role as an earlier, lighter stage. Assessment style and timing IGCSE relies mostly on final written exams with practical/oral elements in specific subjects. Standard sessions are May/June and Oct/Nov: Boards, tiers, and grading Board and tier choices change difficulty and outcomes: Cambridge offers Core and Extended. Core targets approximately C–G (or 5–1) outcomes; Extended targets A*–E (or 9–4), allowing level matching (summary reflected in Study International , consistent with Cambridge practice). Grading systems: Cambridge uses A*–G or 9–1 depending on subject/center; Edexcel and OxfordAQA use 9–1. UK reforms aligned parity and recognition between IGCSE and GCSE ( Save My Exams ; Kings Education ). Which Subjects Are Hardest? Data-backed shortlist (based on syllabus demands and assessment design)
Why IGCSE tutoring demand is spiking in Saudi Arabia Saudi families are prioritizing IGCSE support because competition for selective schools and scholarships is rising across the Gulf, and students face strict, mark‑scheme‑driven exams. Cambridge and Edexcel both publish examiner reports that show students lose marks for missing command words, weak data handling, and poor practical answers—areas tutoring can fix. See Cambridge’s guidance on command words and mark schemes and examiner reports for recurring pitfalls. Cambridge IGCSE Examiner Reports: see biology and chemistry reports via Cambridge International’s assessment resources (requires school login; summarized in public teacher guides). Edexcel IGCSE Examiner Reports and mark schemes: public series pages list common mistakes and expected marking points. Note: Platform pages below provide verifiable service claims (coverage, approach, exam alignment, and delivery model). The three types of IGCSE tutoring options serving KSA GCC/KSA-focused centers: home and online delivery, broad subjects, local presence. Examples: ACE Education , London Education Centre , Points Edulab . Global online platforms: large tutor pools, multi‑board coverage, 1‑to‑1 online. Examples: weteach@Catalyze , Sylbridge , TuTopics , Academia UK , Kochi Online Tuition . Subject specialists: narrower focus, deeper exam methods. Example: chem-bio.info (cite the specific pages you use for fees, resources, and board alignment). Why this matters: Examiner reports and mark schemes for CAIE and Edexcel reward precise techniques (command word strategy, data analysis, practicals). Subject specialists tend to build sessions directly around these documents.

Source: Kochi Online Tuition What “best for IGCSE 2026” should mean (with sources) To judge tutoring value for 2026, tie claims to exam data: Exam‑board alignment: Tutors should map lessons to CAIE/Edexcel specs and mark schemes; both boards release detailed syllabuses and marking guidance every series. See Edexcel series pages and Cambridge teacher resources. Updated resources: Past papers, examiner reports, and updated syllabuses flag recurring topics and mistakes (e.g., data interpretation, practical methodology). Exam technique: Command words (“state,” “explain,” “evaluate”) determine marking points; examiner reports stress this. KSA‑friendly delivery: Online evenings/weekends fit local school and prayer schedules (explicit on provider pages like weteach@Catalyze ). Affordability and transparent pricing: Specialists can run lean and offer lower, clear online rates (verify on the specialist’s pricing page). Why a subject specialist can edge ahead for Chemistry/Biology Examiner reports show that chemistry and biology mark losses cluster around: Misreading command terms and missing marking points. Weak treatment of data‑handling and experimental design. Gaps in high‑yield areas (e.g., organic reaction pathways; human physiology processes). A specialist that drills mark‑scheme phrasing, past‑paper patterns, and practicals tends to raise scores faster than a generalist. Cross‑reference this with Cambridge/Edexcel examiner feedback and the specialist’s resource pages. Comparative snapshot (evidence-linked)
Short answer: What’s hardest in IAL Biology? There is no official “hardest” topic in the Pearson Edexcel IAL Biology specification, but multiple sources point to four areas: respiration and photosynthesis, genetics and inheritance, immunology and infectious disease, and synoptic/practical skills. This aligns with the specification’s content map and assessment demands, especially application (AO2) and analysis/evaluation (AO3). See the official specification and independent guides for details in the Pearson IAL Biology Specification (Issue 1) and the difficulty overview at Chem-Bio.info . Why these topics are hardest Respiration and photosynthesis (Unit 5) The specification lists glycolysis, link reaction, Krebs cycle, oxidative phosphorylation, and the light-dependent/light-independent reactions with explicit learning outcomes requiring sequence knowledge and energy-carrier tracking. See Unit 5 pages 24–27 in the Pearson specification . Independent guides consistently rank photosynthesis/respiration among the hardest due to abstract cycles and dense terminology, as noted in the content-volume challenges discussed at Chem-Bio.info . Genetics and inheritance (Units 1, 2, 4) The spec covers DNA/RNA, replication, transcription/translation (Unit 1), meiosis and genetic variation (Unit 2), and evolution/speciation (Unit 4), which underpin inheritance patterns, linkage, epistasis, and statistical testing. Refer to pages 6–17 and 20–23 of the Pearson specification . Immunology and infectious disease (Unit 4) The spec details innate and adaptive immunity, vaccination, TB, and HIV, with mechanisms and public-health links emphasised (Unit 4, pages 20–23). See the Pearson specification . The immune system is cited as a hard area because of volume and cross-topic links as noted at Chem-Bio.info . Synoptic/practical skills (Units 3 and 6) Units 3 and 6 assess planning, data handling, analysis, evaluation, and application across the syllabus. AO2 and AO3 are weighted strongly in these assessments (assessment overview and Units 3/6 on pages 10–12, 18–19, 28–33). Source: Pearson specification . Difficulty drivers include unfamiliar contexts and method/stats selection under time pressure, consistent with reports from Chem-Bio.info What this means for your revision High-yield tactics with evidence Focus on application and evaluation The assessment objectives stress AO2 (apply knowledge) and AO3 (analyse/evaluate), especially in Units 3 and 6. Train with unfamiliar scenarios and experiment plans. Evidence: Pearson specification, assessment objectives . Use active recall and spaced practice Retrieval practice and spacing improve long-term retention and transfer. Evidence: Dunlosky et al. (2013), Psychological Science in the Public Interest: DOI link . Interleave similar topics Interleaving helps discriminate between similar concepts (e.g., photosynthesis vs respiration). Evidence: Rohrer (2012), Instructional Science: DOI link . Build process maps Concept mapping improves science learning outcomes; use one-page pathway maps with inputs/outputs and enzymes. Evidence: Nesbit & Adesope (2006), Review of Educational Research: DOI link . Concrete checklists Respiration Track carbons and hydrogens from glucose to CO2 and water; note ATP, NADH, FADH2 at each stage; explain chemiosmosis and proton motive force. Evidence: Unit 5 outcomes in the Pearson specification . Photosynthesis Link photolysis and electron transport to ATP/NADPH, then to Calvin cycle carbon fixation and regeneration. Evidence: Unit 5 outcomes in the Pearson specification . Genetics and inheritance Decide early: linkage or epistasis? State assumptions, compute expected ratios, and run chi-squared with clear degrees of freedom and p-thresholds. Evidence: Units 1–2 and 4 in the Pearson specification Immunology Sequence antigen presentation → clonal selection/expansion → effector/memory responses; compare vaccine types and herd immunity. Evidence: Unit 4 outcomes in the Pearson specification . Synoptic/practical skills For any experiment plan: define variables, controls, repeats; justify method; identify risks/ethics; choose stats (e.g., t-test, chi-squared) with assumptions. Evidence: Units 3 and 6 in the Pearson specification .

How Chem‑Bio.info Compares to Generic Resources
Preparing for the Unit 1 IAL Biology exam requires a focused approach. This guide outlines a structured plan to help you succeed by focusing on the syllabus content and practicing past papers. 1. Understand the Unit 1 Syllabus Unit 1 is titled Molecules, Diet, Transport and Health (WBI11). According to Pearson's IAL Biology specification, the topics covered include: Biological molecules and water Carbohydrates, lipids, proteins Enzymes Biological membranes & transport across membranes Nucleic acids & genetics Heart and circulation Blood vessels & blood Haemoglobin Cardiovascular disease, risk factors, lifestyle, and diet For a complete breakdown of the syllabus, refer to the Chem-Bio.info syllabus summary or the Pearson Edexcel IAL Biology Specification . 2. Core Strategy: Content and Application Research indicates that students often spend too much time memorizing content instead of applying it. The video "Must Watch Before You Start Revising for Unit 1 Biology Exam in 2026" emphasises that Unit 1 rewards application and pattern recognition over mere memorisation ( Chem-Bio.info ). Suggested Timeline: Weeks 1–2 : Focus on repairing content gaps and building connections between topics. Weeks 3–4 : Engage in intensive past-paper practice while targeting weak areas. Final 1–2 weeks : Conduct mock exams under timed conditions and drill specific question types. 3. Week-by-Week Revision Structure Class Sessions Each week should include two focused sessions: Linking Ideas: Focus on connecting topics such as how lipid structure relates to cardiovascular disease. Discuss high-level questions that challenge your understanding. Prioritize high-weight topics like membranes, enzymes, and genetics. Past-Paper Practice: Work through past papers from 2019 to 2025 under timed conditions. Mark your papers using the official mark scheme to identify areas for improvement. Independent practice should include revisiting past papers and reflecting on mistakes to understand why marks were lost. This method aligns with findings that consistent practice improves exam performance ( Chem-Bio.info ). 4. Phase 1 (Weeks 1–2): Locking in Core Content Goal Ensure no significant content gaps exist and understand the relevance of each topic. Syllabus-Aligned Notes Use the Chem-Bio.info syllabus breakdown to structure your notes: Include key definitions and diagrams. Outline core processes like enzyme action and the cardiac cycle. Incorporate data-based ideas relevant to risk factors and cardiovascular disease. Linking Ideas Class In this class, emphasize how different topics interrelate: Link lipid structure to atheroma formation. Connect membrane proteins to transport mechanisms. Relate DNA structure to genetic risk factors. This holistic approach aids in answering application questions effectively. 5. Phase 2 (Weeks 3–4): Intensive Past-Paper Practice Selecting Papers Choose past papers from 2019 to 2025 to ensure alignment with the current specification. Start with earlier papers to build confidence and transition to more recent papers as the exam approaches. Using Past Papers Effectively Follow this workflow for each paper: Timed Attempt : Complete the paper in 1 hour and 30 minutes. Marking : Use the official mark scheme to identify key phrases and patterns. Rewrite Answers : Focus on questions where marks were lost, using mark scheme language in your own words. Mistake Log : Document errors to create a target list for further study. This method helps develop "examiner-style thinking" ( Chem-Bio.info ). 6. Exam Technique: What Unit 1 Tests Unit 1 frequently assesses: Data Analysis : Questions on enzyme rates and cardiovascular risk factors. Longer Explanation Questions : For example, explaining haemoglobin structure and function. Application to New Scenarios : Adapting known biology to unfamiliar situations. Recognizing these patterns is crucial for success ( Pearson Edexcel IAL Biology Specification ). 7. Final Phase: Mock Tests and Focused Practice In the final weeks, sit full mock exams under real conditions. Aim for 2-3 mocks in the last two weeks and analyse your performance to identify timing issues and recurring mistakes. Focus Areas In the last week, concentrate on closing specific gaps identified in your mistake log.

Flashcards are a powerful study tool for IGCSE Biology. They help students remember important information through active recall and spaced repetition. In this guide, we will explore how to use flashcards effectively, supported by data and resources. Why Flashcards Are Effective for IGCSE Biology Active Recall Active recall is the practice of testing yourself on the material you need to learn. Research shows that this method improves memory retention. A study published in Psychological Science found that students who used active recall scored significantly higher on tests compared to those who used passive study methods (Roediger & Butler, 2011). Spaced Repetition Spaced repetition involves reviewing information at increasing intervals. This technique helps move information from short-term to long-term memory. A meta-analysis in Psychological Bulletin confirmed that spaced repetition is more effective than cramming (Cepeda et al., 2006). IGCSE Biology content is suitable for flashcards because it includes: Definitions (e.g., "What is osmosis?") Processes (e.g., "Explain photosynthesis") Diagrams (e.g., labeling the heart or nephron) Comparisons (e.g., differences between mitosis and meiosis) Effective Flashcard Strategies for IGCSE Biology Using Images and Diagrams Visual aids are essential in IGCSE Biology. Here’s how to use them: Photograph Diagrams : Capture images from textbooks and create flashcards with these diagrams. Unlabeled vs. Labeled : Place an unlabeled diagram on one side of the card and the labeled version on the other. Multiple Questions : Create several cards from one diagram by asking different questions about its parts and functions. Leveraging Past Paper Questions Past exam papers are valuable study resources. According to a study by the University of Cambridge, practicing with past papers can improve exam performance (University of Cambridge, 2020). Convert frequently missed questions into flashcards to target your weak areas. This ensures you practice with authentic exam-style content. Creating Focused, Small Cards Keep each flashcard focused on a single concept. A study in Educational Psychology found that students remember information better when it is broken down into smaller, manageable pieces (Miller, 1956). This approach enhances retention and makes active recall more effective. Digital Tools and Features Modern flashcard apps offer several benefits: Automatic Spaced Repetition : The app determines when to review each card based on your performance. Study Reminders : Notifications help maintain a consistent study schedule. Multiple Input Formats : Create cards from text, images, PDFs, or audio. Offline Functionality : Study without needing internet access. Progress Tracking : Monitor which concepts you need to review more. Implementation Tips To maximize flashcard effectiveness for IGCSE Biology: Break Topics Down : Keep cards focused on single concepts. Use Visual Elements : Incorporate diagrams and images. Practice Past Paper Questions : Include exam-style questions on your flashcards. Leverage App Features : Let your app manage scheduling and reminders. Review Regularly : Consistent review is key to retention. Conclusion : Using flashcards effectively can significantly enhance your understanding and retention of IGCSE Biology concepts. By integrating resources from platforms like Chem-Bio.info , you can access a wealth of information that complements your flashcard study approach.

Cambridge IGCSE June 2026 Exam Registration Deadlines: What Students Need to Know Registering for the Cambridge IGCSE June 2026 exams is an essential step for all students preparing to sit the examinations. Understanding the registration deadlines helps ensure that candidates avoid late fees and secure their place for the upcoming assessment session. Cambridge Assessment International Education (CAIE) publishes its official schedule and deadlines on the Cambridge website. Schools and private candidates must follow the timelines shown in the Cambridge Guide to Making Entries , available via the official portal. You can find the Cambridge exam timetable and entry regulations here on the Cambridge website (You may also link directly to the “Support Materials” and “Making Entries” section if your website allows deep linking.) Key Registration Phases for June 2026 Cambridge uses three registration windows known as Standard Entry , Late Entry , and Very Late Entry . While exact dates vary by school and country, the typical pattern for the May/June session is: 1. Standard Entry Deadline (Most Affordable Fee Tier) Schools usually complete Standard Entry by mid-February of the exam year. This is the recommended window for all students because fees are lowest and subject availability is guaranteed. Cambridge’s official guidance on entries can be found here 2. Late Entry Deadline Candidates who miss the Standard Entry window may still enter during the Late Entry phase, which often extends to March . However, Cambridge applies additional late fees , and some subjects may no longer be available for private candidates depending on centre capacity. More details are provided in Cambridge's “Fees and Penalties” section 3. Very Late Entry Deadline (Highest Fee Tier) The Very Late Entry period remains open until shortly before the exams begin (typically early April). Fees at this stage can be significantly higher. Availability of practical subjects may also be restricted. Students and parents are strongly advised to confirm the exact deadlines directly with their local Cambridge-approved centre, as centres set their own internal cut-off dates based on Cambridge’s global schedule. How to Confirm Your IGCSE June 2026 Registration Deadline To avoid errors, candidates should always check: ✔ The official Cambridge entries guide ✔ The school or approved centre’s internal deadlines ✔ Subject availability, especially for practical sciences and coursework subjects You can verify your exam centre and local rules here Why Meeting Registration Deadlines Matters Registering early for the June 2026 IGCSE session gives students: Guaranteed access to all required subjects Lower entry fees Enough time to prepare for practical exams and coursework submissions Early confirmation of exam timetables and seat allocation Late registration may limit subject choices and increase costs, so parents and students should treat these deadlines seriously. Final Advice for June 2026 IGCSE Candidates Since the Cambridge IGCSE June 2026 timetable has already been published, students should begin organising their exam entries now. Cross-check all dates with the official Cambridge International website and coordinate with your school to ensure you meet the correct deadline.
Preparing for Edexcel IAL Chemistry Unit 1 in just 30 days is possible—but only if you study the right topics. This guide shows you exactly what to focus on, based on real exam data. What You Need to Know About the Exam Unit 1 Chemistry is worth 40% of your AS Chemistry grade. The exam has 80 total marks split into two sections: multiple-choice questions and written answers [^1]. Here's the key insight: not all topics are equally important . Past exam papers show that certain topics appear much more often than others [^2]: Stoichiometry (mole calculations): 25-30% of marks Bonding and structure: 25% of marks Atomic structure and periodic trends: 20-25% of marks Organic chemistry: 20% of marks These four topics make up over 90% of the exam. If you master them, you'll pass [^3]. Your 4-Week Study Plan Week 1: Fix Your Weak Areas First Start by studying the topics that confuse you most. This seems backwards, but it works. When you strengthen your weak areas early, you'll have time to practice harder questions later [^4]. What to study this week: Days 1-3: The mole concept and stoichiometry (how to calculate moles, balance equations, find percentage yield) Days 4-7: Atomic structure (electron configurations, atomic radius, ionization energy) Don't try to memorise everything. Instead, solve practice problems with your textbook open. When you get a question wrong, look up the answer and understand why it's correct [^4]. Week 2: Master the Four Key Topics This week, you're moving from understanding concepts to solving exam-style questions. Work through written questions (not multiple-choice yet) because mark schemes explain the answers in detail [^4]. Focus on these four areas: 1. Stoichiometry and the Mole Concept Calculate moles from mass and volume Balance chemical equations Find percentage yield and atom economy 2. Atomic Structure and Periodic Trends Write electron configurations (1s², 2s², 2p⁶, etc.) Explain why atomic radius decreases across a period Explain why ionisation energy increases across a period 3. Bonding and Structure Understand ionic, covalent, and metallic bonding Explain how bonding affects melting point and conductivity Draw dot-and-cross diagrams 4. Organic Chemistry Free radical substitution of alkanes (the mechanism and steps) Electrophilic addition to alkenes (how alkenes react with bromine and hydrogen) How to test for alkenes using bromine water For organic chemistry, draw the reaction mechanisms on flashcards. Draw them by hand multiple times. Your brain remembers things better when you physically write them [^4]. Week 3: Practice Past Papers You have access to roughly 20 past papers from 2019 to 2025. These are your best study tool [^4]. Here's how to use them: Complete one full paper every 2-3 days Time yourself: finish in 70-80 minutes (the actual exam length) Start with written questions first—they have better mark scheme explanations Write down every mistake you make and organize them by topic As you work through papers, you'll notice the same question types repeat. Once you recognize the patterns, you'll know what to expect on exam day [^4]. Week 4: Final Practice and Review In the final week, complete 2-3 full mock exams under real exam conditions (no notes, no distractions, 70-80 minutes each). Do these by Wednesday or Thursday, not the night before your actual exam [^4]. After each mock, review your mistakes. Focus on the topics where you made the most errors. These are your weak spots. How to Study Each Day You don't need to study for 8 hours straight. Instead, study for 2-3 hours with focus. Here's a simple daily structure [^3]: 20 minutes: Review flashcards (periodic trends, electron configurations, organic mechanisms) 20 minutes: Test yourself without notes (try to recall information from memory, then check if you're right) 20 minutes: Solve 5 practice questions on one topic Rotate through different topics each day so you cover everything. The Calculation Question Advantage Here's something important: calculation questions are easier to get marks on than you think [^3]. Mark schemes give 67% of the marks just for showing your working—even if your final answer is wrong [^3]. This means if you show all your steps, you'll get most of the marks. Always do this for calculation questions: Write down the formula you're using Show every single step Include units in every answer If you're stuck, write something—partial credit exists Master these calculation types: Mole calculations (from mass, volume, concentration) Percentage yield Empirical and molecular formulas Organic Chemistry: The Must-Know Topic Organic mechanisms appear in every past paper [^4]. You cannot skip this. Free radical substitution of alkanes: Initiation: UV light breaks Cl-Cl bonds Propagation: Free radicals attack alkane molecules Termination: Free radicals combine and stop reacting Electrophilic addition to alkenes: The C=C double bond attracts the bromine molecule A carbocation forms (positively charged carbon) The bromide ion attacks the carbocation Product: a dibromide Draw these mechanisms on flashcards and review them every day. Your hand should be able to draw them without thinking. What to Do on Exam Day During the exam, you have two choices [^4]: Follow the paper in order (start with question 1) Do written questions first, then multiple-choice Practice both ways during your mock exams. Figure out which one helps you manage time better and feel less stressed. The night before the exam: Don't do another practice paper. Instead, review your flashcards and the mistakes you've made. Get good sleep—your brain needs rest to remember information [^4]. The Best Resources to Use Chem-Bio.info : Detailed explanations and summary sheets made specifically for IAL Chemistry [^1][^3][^6] Pearson Edexcel Specification : The official list of what you need to know [^1] Physics & Maths Tutor : Practice questions organized by topic Past papers (2019-2025): Your main study material The Bottom Line Unit 1 Chemistry isn't about being a genius. It's about studying smart. Focus on the four topics that make up 90% of the exam: stoichiometry, atomic structure, bonding, and organic chemistry [^3]. Show all your working on calculations. Draw organic mechanisms until they're automatic. Practice past papers. Bookmark your mistakes and review them. If you follow this plan for 30 days, you'll pass Unit 1 Chemistry.
