This page contains all 35 available files for Cambridge IGCSE Sciences Co ordinated Double (0654) — 2021 Oct-Nov. That includes 16 question papers and 16 mark schemes, plus 1 examiner report, 1 grade threshold document. Every file is the official document published by Cambridge and is free to download as a PDF — no account or payment required.

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.

Cambridge filenames follow a consistent pattern: `0654_[type]_[paper][variant]_w21`. The paper number indicates which component of the syllabus is being examined (e.g., Paper 2 = structured questions), while the variant number (1, 2, or 3) indicates the time zone administration. To find matching question paper and mark scheme pairs, match the last two digits — for example, `0654_qp_42` pairs with `0654_ms_42`.

Time management within the exam is as important as subject knowledge. When practising with this paper, track how long you spend per question and compare it to the marks allocated. If you're spending disproportionate time on low-mark questions, that's a technique issue that past paper practice under timed conditions will fix. The examiner report highlights which questions were poorly done by the cohort — if you also struggled with those questions, it confirms they need targeted attention.

Match by paper number and variant — the last two digits of the filename. For example, 0654_qp_42 (Question Paper, Paper 4, Variant 2) matches with 0654_ms_42 (Mark Scheme, Paper 4, Variant 2). Session codes: s = May/June, w = Oct/Nov, m = Feb/March.

Cambridge administers different variants of the same paper in different time zones to prevent paper leaks. Variant 1, 2, and 3 are equivalent in difficulty and syllabus coverage — you can practise with any variant regardless of your region.
