If you want clear, exam-ready revision for Edexcel IAL Biology, ChemBio by Hosni is a strong choice. The notes are updated, aligned to mark schemes, and include practice tools. Below is a straightforward review with sources linked.

Why These Notes Stand Out
Feature What you get Evidence
Regular updates Syllabus-specific Notes revised for the current Edexcel IAL Biology syllabus The 2024–2025 notes page states annual updates — chem-bio.info
Mark scheme focus Exam-oriented Bullet points match mark scheme wording to target marks Emphasis on examiner keywords — YouTube overview
Interactive revision Quizzes & flashcards Built-in summaries, quizzes, and flashcards for each topic Listed features and walkthroughs — Notes page, AS notes video
Key terms highlighted Definitions Clear tagging of definitions and must‑know terms Demonstrated in previews — YouTube overview
Practicals covered Units 3 & 6 Dedicated sections for Units 3 and 6 practicals Coverage shown on product page and demos — Notes page, Channel

Why These Notes Stand Out

If you want clear, exam-ready revision for Edexcel IAL Biology, ChemBio by Hosni is a strong choice. The notes are updated, aligned to mark schemes, and include practice tools. Below is a straightforward review with sources linked.

What’s Inside
Section What it includes Why it matters Evidence
Topic summaries Short, clear explanations (e.g., water polarity, hydrogen bonding, transport in plants) Speeds up first-pass revision and focuses key terms Samples shown in previews — overview video
Mark scheme bullets Points phrased with exam-friendly command words Helps match scoring phrases used by examiners Walkthroughs stress mark-scheme phrasing — AS notes video
Quizzes & flashcards Self-check after each topic; active recall practice Improves retention vs. rereading Feature lists on site + retrieval-practice research (Karpicke & Blunt, 2011) — notes page
Visual aids Diagrams and highlighted definitions Aids memory and quick review Demonstrated in previews — overview video
Practicals (Units 3 & 6) Methods, variables, controls, risks, data analysis Matches assessed practical skills Listed on product page and in channel demos — notes page, channel

About “90% retention”: The channel claims high retention with active recall tools. While product claims vary, education research shows retrieval practice improves long-term memory versus rereading (e.g., Karpicke & Blunt, 2011; not specific to this product). Use the quizzes/flashcards to get these gains. Product claim reference: YouTube overview.

  • Research reference (education science): Karpicke, J. D., & Blunt, J. R. (2011). “Retrieval practice produces more learning than elaborative studying with concept mapping.” Science, 331(6018), 772–775. DOI: 10.1126/science.1199327


How To Use These Notes Effectively

  • Start with topic summaries, then test yourself.

Read the summary, then do the quiz or flashcards for that topic. Retrieval practice improves retention vs. rereading alone (Karpicke & Blunt, 2011. DOI above).

Mirror mark schemes in your answers.

After each quiz, write a 3–4 line answer using the exact key terms shown in the notes and compare with past paper mark schemes. The videos show this workflow AS notes video.

Drill practicals weekly.

For Units 3 and 6, cover variables, controls, risks, and data analysis. The notes and channel demos align to these skills Notes page, Channel.

Close gaps with official materials.

Use Edexcel past papers and examiners’ reports to verify phrasing and required detail. This triangulation is standard best practice in exam prep.


Where to Get Them


Bottom line: These notes are updated, mark-scheme focused, and include active recall tools. Use them with past papers and examiner reports for the best results. Sources linked above.
