GCSE Notes
About These Notes
These notes are written with the rigour of an undergraduate textbook, but targeted at the GCSE Syllabus. Every definition is precise, every result is derived (or its derivation is sketched with Enough detail for you to complete it), and every formula is justified from first principles.
The goal is not just exam preparation — it is to build the deep mathematical, scientific, literary, And logical intuition that makes exam questions feel like applications of things you truly Understand.
Exam Boards Covered
| Board | Specification | Notes |
|---|---|---|
| AQA | 8702 (English Lit), 8300 (Maths), 8463 (Physics), 8462 (Chemistry), 8461 (Biology), 8525 (CS) | Content annotated where AQA diverges |
| Edexcel (Pearson) | 1ET0 (English Lit), 1MA1 (Maths), 1PH0 (Physics), 1CH0 (Chemistry), 1BI0 (Biology), 1CP2 (CS) | Content annotated where Edexcel diverges |
| OCR | J352 (English Lit), J560 (Maths), J259 (Physics), J258 (Chemistry), J257 (Biology), J277 (CS) | Content annotated where OCR diverges |
| WJEC/Eduqas | 7222 (English Lit), 3000U (Maths), C400 (Physics), C420 (Chemistry), C410 (Biology), 3510QS (CS) | Content annotated where WJEC diverges |
Where boards agree on a topic (which is most of the core content), you will find a single unified treatment. Where they diverge — in specific required practicals, formulae given in data sheets, or assessment style — differences are noted in labelled callouts.
How to Use These Notes
- Read the theory first. Each topic builds on previous ones. Follow the sidebar order.
- Work through the derivations. Don’t skip them — understanding why a result holds is what separates grade 9 students from the rest.
- Attempt the problem sets. Each topic ends with multi-step problems that test deep understanding, not just recall.
- Use the common pitfalls sections. These highlight the errors that examiners see year after year.
Subjects
- English Literature — Shakespeare, the 19th-century novel, modern texts and poetry, and essay writing
- Mathematics — Number, algebra, geometry, statistics, and ratio, proportion, and rates of change
- Physics — Energy, forces, waves, electricity, and magnetism and electromagnetism
- Chemistry — Atomic structure, bonding, chemical reactions, quantitative chemistry, and organic chemistry
- Biology — Cell biology, organisation, bioenergetics, inheritance, variation and evolution, and ecology
- Computer Science — Algorithms, programming, data representation, computer systems, and networks
Summary
The key principles covered in this topic are linked in the sub-pages above. Focus on understanding the definitions, applying the formulas or frameworks, and evaluating strengths and limitations of each approach.
Worked Examples
Worked examples demonstrating the application of key concepts are covered in the detailed sub-pages linked above.
Common Pitfalls
- Confusing terminology or concepts that appear similar but have distinct meanings.
- Overlooking key assumptions or boundary conditions that limit applicability.
