All 40 Cambridge IGCSE Chemistry (0620) papers from the 2018 Oct-Nov session are available on this page. You'll find 18 question papers and 18 mark schemes, along with 1 grade threshold document. Download any file instantly — these are the same official papers sat by students worldwide in 2018.

The October/November series is primarily taken by students in South Asia and sub-Saharan Africa. It follows the same syllabus as May/June but is typically offered in fewer subjects and with a smaller candidate pool, especially for O Level. IGCSE Oct/Nov papers follow the same variant numbering system as May/June.

In Cambridge filename conventions, 'qp' denotes a question paper, 'ms' a mark scheme, 'er' an examiner report, and 'gt' grade thresholds. The session code in the filename — 's' for May/June, 'w' for Oct/Nov, 'm' for March — combined with the last two digits of the year, gives you `w18`. So `0620_qp_42_w18` is Paper 4, Variant 2 of this session.

Past papers are most useful as diagnostic tools rather than just extra practice. After completing each paper, sort your errors into three categories: topics you don't know well enough, question types where your technique needs work, and topics where you lost marks to careless mistakes. Each category needs a different fix — content review, technique drill, or exam discipline respectively.
