Which IGCSE Course Does Your Child Need?

Cambridge and Edexcel set different papers and use different syllabus codes, so the solved papers are different too. Check the board first, then open the subject.

Sitting Cambridge?

Your child's exam entry shows 0610 or 0970 for Biology, 0620 or 0971 for Chemistry. Cambridge sets Papers 2, 4 and 6, including the Alternative to Practical.

Sitting Edexcel?

Your child's exam entry shows 4BI1 for Biology or 4CH1 for Chemistry. Edexcel sets Papers 1 and 2, and the courses suit both the linear and modular routes.

The Real Problem

Why Students Cannot Rely Only on Mark Schemes

Many students practise past papers, check the mark scheme, and still do not understand why their answer lost marks. Usually the problem is not the student — it is the mark scheme.

Written for markers, not learners

Mark schemes exist so examiners can mark consistently. They were never designed to teach a student how to build an answer, which is why reading one rarely fixes the mistake.

They show the answer, not the thinking

A mark scheme often gives the final answer with no route to it — a real problem in Chemistry calculations, graph work, practical questions and long-answer Biology.

So the same mistake repeats

Without an explanation, students keep repeating papers without improving. They check the answer, move on, and make the same mistake again in the next paper.

Every course here closes that gap: full written answers in student-friendly language, plus videos where students solve along, pause and repeat until the method sticks.

What's Included

The Same Standard in Every Course

Whichever board and subject you choose, the course is built the same way — from the mark scheme backwards.

Every paper fully solved

Complete worked papers from 2019 to the latest 2026 sessions — not selected questions, and not one-line answers.

Classified by topic

The same questions sorted by syllabus topic, so revision can target one weak area instead of wandering through whole papers.

Video walkthroughs

Students solve along with me — pause, rewind, repeat — and see the thinking behind the answer, not just the answer.

A practice app

Revise by topic or by year, or type in any exam question number and jump straight to its worked answer.

Practical papers too

Cambridge Paper 6 and the Edexcel practical questions are answered in full — method, variables, tables, graphs, conclusions.

Updates and support

New sessions are added at no extra cost, with direct WhatsApp support and two years of access.

FAQ

Before You Choose

The school's exam entry names the board and the syllabus code. Cambridge Biology is 0610 or 0970 and Chemistry is 0620 or 0971; Edexcel Biology is 4BI1 and Chemistry is 4CH1. If in doubt, ask the school which code your child is entered for — the papers really are different, so it is worth checking before buying.

The method is identical; the papers are not. The Cambridge courses cover Papers 2, 4 and 6, including the Alternative to Practical. The Edexcel courses cover Papers 1 and 2 and suit both the linear and modular routes. Each course only contains the papers that board actually sets.

Yes. Cambridge Paper 6 (Alternative to Practical) is solved as fully as the theory papers — apparatus, method, variables, recording results, tables, graphs, analysis and evaluation. On the Edexcel side, the practical questions inside Papers 1 and 2 are worked through the same way.

Every series from 2019 up to the latest 2026 sessions is included, and new sessions are added automatically at no extra cost. Access runs for two years, which comfortably covers a full IGCSE cycle.

Yes, and it costs less than buying the two separately. Open either subject page for your board and the two-subject bundle is shown there with its price and saving.

No — they do different jobs. The notes teach the syllabus content; these solved past papers teach how to turn that knowledge into marks under exam conditions. Most students use the notes first and the solved papers in the months before the exam.
