Frequently asked questions
What is a solved past paper?
It is the original exam paper with a full model answer written under every question — using mark-scheme language, with each scoring point ticked, calculations shown step by step, and examiner-report notes on common mistakes.
Which exam boards do you cover?
Edexcel IGCSE (4BI1, 4CH1), Cambridge IGCSE (0610, 0620) and Edexcel International A Level Biology and Chemistry (Units 1–6).
Are answers just copied mark schemes?
No. Mark schemes are written for examiners, not students. These answers translate the mark scheme into full sentences a student can actually write in the exam, and explain why each point scores.
How do I receive the papers?
Instantly. After purchase you get digital access on any device — phone, tablet or laptop — through the Chem Bio library.
Do the solved past papers eBooks get updated?
Yes. The eBooks are living resources — when a new exam series is released, fresh solved papers are added to the collection and your library access is updated, so your package never goes out of date.
Can I use the eBooks on more than one device?
Yes. Your library works on phone, tablet and laptop — start a paper on your phone on the bus and continue on your laptop at home, with the same account.
Can I print the past paper questions?
Yes. Each collection includes a printable questions PDF, so you can attempt the paper on paper under timed exam conditions, then check your work against the solved version on screen.
See how to use IGCSE past papers as a training tool instead of simply checking a score. The video covers mark-scheme interpretation, written-answer structure and how worked solutions help you recognise where marks are being lost.
