IGCSE Chemistry is a subject that frequently raises questions regarding its difficulty. With a reputation for being one of the more challenging IGCSE subjects, many students wonder if they can successfully navigate its complexities. This blog aims to explore the challenges of IGCSE Chemistry and provide effective strategies for success.


Understanding the Difficulty of IGCSE Chemistry

Comparison with Other Subjects

IGCSE Chemistry is often viewed as more challenging compared to IGCSE Biology and is consistently ranked among the top five most difficult IGCSE subjects. This perception stems from the depth and breadth of the content covered in the syllabus, which can be daunting for many students.

Key Challenges

The subject encompasses complex topics such as atomic structure, chemical bonding, and the behaviour of gases. These concepts can be abstract and difficult to visualise, making understanding a significant hurdle. Additionally, the extensive syllabus requires students to memorise numerous formulas and apply scientific principles to unfamiliar scenarios.

Pass Rates and Implications

Despite its challenges, the pass rate for IGCSE Chemistry is relatively high, ranging between 82% and 85%. This statistic indicates that while the subject poses difficulties, it remains achievable for most students with the right approach and dedication.


Strategies for Success in IGCSE Chemistry

Understand the Syllabus

Familiarising oneself with the official syllabus is crucial. It outlines the topics covered and the command words frequently used in exam questions. Understanding these expectations helps students focus their revision effectively.

Use the right resources

It is highly recommended that you use ready-made notes instead of writing your own from scratch. This approach saves time and ensures that you have all the necessary information in one place. Among the various IGCSE Chemistry notes available online, The Complete Notes for IGCSE Chemistry receive the highest reviews from students. The author regularly updates these notes with the latest mark schemes and examiner reports. The notes are concise, omitting any extraneous information that is unlikely to appear in your exam. Additionally, the latest edition now includes videos that explain the key concepts in IGCSE Chemistry.

Master Core Concepts

Rather than relying solely on memorisation, students should aim to understand key concepts like atomic structure and chemical bonding. Employing diagrams and real-life examples can aid in visualising these abstract ideas.

Practice Past Papers

Regular practice with past exam papers is essential. This not only familiarises students with the format of questions but also helps them learn how to structure their answers to meet examiner expectations.

Utilise Mark Schemes

Studying mark schemes is invaluable for understanding what earns marks in exams. This knowledge helps students avoid losing points due to incomplete or vague responses.

Active Revision Techniques

Active revision methods, such as using flashcards, summary notes, and mind maps, can reinforce memory retention. Teaching concepts to peers or explaining them aloud can further deepen understanding.

Address Weak Areas

It is important for students to identify topics they struggle with early on and allocate additional time for improvement. Seeking help from teachers, tutors, or online resources can provide necessary support.

Time Management

Creating a revision timetable and adhering to it is vital. Breaking down the syllabus into manageable sections and reviewing content regularly can prevent last-minute cramming.

Exam Technique

During the exam, students should read questions carefully, underline key command words, and plan their answers. Effective time management is crucial to ensure that all questions are attempted.


Insights from the IGCSE Chemistry Master Class

Command Words in Questions

Understanding command words such as “describe,” “explain,” and “calculate” is critical. The IGCSE Chemistry Master Class emphasises the importance of knowing what each term entails and how it relates to the syllabus.

Regular Practice

Consistent practice with past papers and careful review of mark schemes align students’ answers with examiner expectations, enhancing their chances of success.

Active Revision

Active learning techniques, rather than passive reading, are vital for retaining information and mastering the material.

Pearson Edexcel enhanced grading vs contingency graphic for 2026 exams
by Hosni Showike 9 April 2026
For students in affected countries such as Kuwait, UAE, Bahrain, and Lebanon, the 2026 exam session includes special arrangements confirmed by Pearson . These changes introduce two official grading routes: Enhanced Grading and International Contingency Grading (ICG) . Understanding these is essential because your final grade — and your revision strategy — depends on which route applies to you. Official Pearson Guidance for Affected Countries According to Pearson , when exams cannot proceed as normal in affected regions: Students may receive grades using existing unit results (Enhanced Grading) Or through school-submitted evidence (Contingency Grading) You can read the official policy here This confirms that grading remains structured, evidence-based, and regulated — not estimated or random. 🟣 Enhanced Grading (No Exam Required) Enhanced grading is the simplest pathway , but only available if you meet specific conditions. No exams required Based entirely on previous unit results Final grade awarded directly by the exam board To qualify: AS students must have already completed Unit 1 A Level students must have already completed Unit 4 If you meet these requirements and choose to cash-in , your grade can be calculated without further exams. πŸ‘‰ In simple terms: If you have already demonstrated your level, Pearson may use that performance to award your final grade. πŸ”΅ International Contingency Grading (ICG) Contingency grading is used when enhanced grading is not possible . Schools submit evidence of student performance This includes mock exams, past papers, and controlled assessments Pearson examiners review this evidence to award final grades This applies when: You are retaking units You haven’t completed required units (Unit 1 or Unit 4) You are entering multiple units together without prior results πŸ‘‰ This is NOT predicted grades — it is evidence-based grading under exam conditions . Key Scenarios You Must Understand AS Students Completed Unit 1 + taking Units 2 & 3 → Enhanced Grading (if cash-in) Retaking Unit 1 → Contingency Grading A Level Students Completed AS (Units 1–3) + Unit 4 + taking Units 5 & 6 → Enhanced Grading (full A Level) Completed AS but not cashing in → Contingency Grading Mixed or Full Entries Taking all 6 units together → Contingency Grading Taking 4–5 units only → Contingency Grading πŸ‘‰ Core rule from Pearson: If suitable previous results exist → Enhanced Grading If not → Contingency Grading IGCSE Modular Students For modular IGCSE pathways: Taking both units in the same session → Contingency Grading Taking Unit 2 after Unit 1 → Final grade may be awarded directly Taking only Unit 1 → Exam postponed to a later session (e.g. October) Private Candidates (Important Clarification) According to the British Council : Private candidates will still sit exams as usual No enhanced or contingency grading applies Standard exam route remains in place πŸ‘‰ Exams are still considered the most reliable assessment method for private candidates. How This Affects Your Revision Strategy This update is not just administrative — it directly impacts how you should study. If you are under Contingency Grading: Your mock exams are critical Every assessment becomes evidence You must treat all school tests like real exams If you qualify for Enhanced Grading: Your past results determine your final grade Focus on securing strong outcomes in completed units Final Advice for Students in Affected Countries The biggest mistake right now is not knowing which pathway applies to you . Before continuing youar revision: Confirm your completed units Check if you meet Enhanced Grading conditions Speak to your school about your assessment route Students who understand this early can adjust their strategy, focus on the right assessments, and maximise their final grade — even under changing exam conditions.
IGCSE 2026 exam update portfolio of evidence guide

What Just Happened — and Why It Matters to Every IGCSE Student On 2 April 2026, Cambridge International Education sent a circular to schools across the UAE confirming the news in plain terms: "We will not move back to running exams in your country in the June 2026 series." That sentence landed hard. But before panic sets in, read this carefully — because what happens next affects not just students in the UAE, but every IGCSE student sitting exams worldwide in June 2026. Pearson Edexcel has cancelled in-person exams across the UAE, Bahrain, Kuwait and Lebanon for the May/June 2026 series. OxfordAQA confirmed the same for UAE, Kuwait and Bahrain. The widespread cancellations come amid continued regional tensions linked to the ongoing conflict, which has already led to disruptions across multiple sectors. Over 120 schools across the UAE alone offer Cambridge programmes. The numbers across Kuwait, Bahrain and Lebanon add thousands more. This is one of the largest exam disruptions the British curriculum community in the Middle East has ever faced. Here is what you need to understand — clearly, without the noise. Who Is Affected Cambridge International has confirmed that its IGCSE and International A-Level examinations scheduled for summer 2026 in the UAE will not go ahead. The cancellations cover Cambridge IGCSE, Cambridge O Level, Cambridge International AS and A Level, and the Cambridge IPQ. Pearson Edexcel confirmed cancellations in the UAE, Bahrain, Kuwait and Lebanon. OxfordAQA confirmed the same for UAE, Kuwait and Bahrain. If your school follows any of these boards and you are based in one of these four countries — this announcement applies to you directly. Your school will receive official guidance. Until then, read on. What Is a Portfolio of Evidence — and What It Is NOT This is the part most students and parents get wrong. Listen carefully. Instead of a student sitting a timed paper in an exam hall, the school compiles a body of work that represents what that student has actually done and learned throughout the year. This goes to Cambridge, who use it to determine a final grade. A portfolio is not predicted grades. It is not your teacher picking your best marks. It is not a free pass. Each portfolio will consist of three substantial pieces of evidence per subject, which schools will submit to Cambridge International Education for external marking and grading. Each piece must be completed under proper exam conditions, lasting around one hour. That means mock exams in most cases — and your school will likely schedule new sittings to collect the evidence students need. Cambridge has also set strict rules on what counts: The paper cannot be the actual June 2026 exam paper It cannot be a multiple-choice paper You cannot redo tasks to improve your performance Your teacher will not simply pick your three highest scores. They will select work that represents your consistent, real level of performance . All three pieces carry equal weight — each counts for one third of your final grade. One weak performance matters. Take every sitting seriously. Cambridge examiners then review the submitted evidence and award grades in a way that reflects candidates' demonstrated work. Your teacher marks first. Cambridge marks second. The standard used is the same as a real exam. What This Means for How You Should Study Right Now Here is the shift in thinking that changes everything: every past paper question you practise right now could appear in your portfolio assessment. Because schools will base their evidence-gathering sessions on past papers, your revision is no longer just preparation — it is directly connected to the work that will be submitted for your final grade. Work under timed conditions. Follow mark schemes precisely. Treat every practice session as the real thing. This is exactly why structured, exam-focused revision matters more now than it ever has. If you are behind or need to catch up fast, the IGCSE Live Crash Course at Chem-Bio runs live weekly classes in Biology and Chemistry, built entirely around past papers, mark scheme language, and exam technique — the exact skills that will determine your portfolio grade. Sessions are recorded, so you can revisit them as many times as you need. What About Grade Boundaries — Does This Affect Students Sitting Real Exams? This question is circulating everywhere, and the answer deserves a straight response. Grade boundaries are not fixed . They are set after each exam series using statistical evidence and expert judgment so that candidates are not disadvantaged if their papers are harder than in previous years. Students submitting portfolios are assessed separately by Cambridge examiners using the same marking standards as traditional exams. Their grades are not pooled with the results of students sitting written papers. Cambridge converts the raw mark into a percentage uniform mark (PUM) out of 100, which shows where a student sits inside the grade they achieved. The bottom line: if you are sitting written exams elsewhere in the world, your grade boundaries will be set based on your exam performance — not on portfolio results from affected regions. The two groups are assessed independently. Your grade is still in your hands. Will These Grades Be Accepted by Universities? Yes — and this needs to be said clearly. UK universities are familiar with alternative grading scenarios. Cambridge qualifications awarded through a portfolio route are still Cambridge qualifications. The grade on the certificate is what universities see. They do not receive a note saying the grade was awarded via portfolio. Cambridge has been clear that candidates can receive certification for their work and progress with their education. The certification pathway is intact. Students will still receive Cambridge qualifications. The route has changed — not the destination. What You Should Do Right Now Stop refreshing WhatsApp groups. Start acting. If you are in an affected country: Complete all coursework properly — it goes directly into your portfolio Ask your school's exams officer what evidence has already been collected Begin practising past papers under timed, closed-book conditions immediately Treat every mock sitting as a real exam — because it now is one If you are sitting written exams elsewhere: Nothing about your exam format has changed Focus entirely on your revision — grade boundaries will be fair Use the next few weeks to maximise your mark For both groups — if you need structured support for IGCSE Biology or Chemistry, the Chem-Bio Live Classes are running now. Live sessions, recorded replays, past paper drills, and mark scheme coaching — designed specifically for the June 2026 exam window. Join before the next session fills up. The Bottom Line Whether you are submitting a portfolio or sitting a written paper, one thing has not changed: your grade reflects the work you put in . The system has shifted around you — but your effort, your practice, and your exam technique still determine the outcome. Cambridge has confirmed the certification pathway is intact. Universities will accept the results. The examiners marking your portfolio use the same standards as always. So stop worrying about what you cannot control. Start working on what you can. πŸ‘‰ Join the IGCSE Live Crash Course and get exam-ready — whatever route your school is taking.
