Common questions

Are these real Cambridge IGCSE Chemistry Core 0620 past paper questions?

Yes. Every worksheet is made from real Cambridge past paper questions, grouped by syllabus topic and subtopic, so a student can practise one topic at a time instead of a whole paper.

Do the worksheets come with marking schemes?

Yes. Each worksheet has its own marking scheme, and every topic has revision notes covering the key ideas, common mistakes and the question types examiners set most.

Are the Cambridge IGCSE Chemistry Core 0620 worksheets free?

The worksheets for the first two topics are free to read online. A free trial opens every worksheet, marking scheme and revision note in every subject for 15 days, with no card needed. After that, keep the subjects you need, 30 days at a time.

How should I use topical past papers?

Pick the topic you are revising and read its revision notes first. Then do the worksheet under timed conditions, mark it with the marking scheme, and redo every question where marks were lost a few days later.
