Overview
“How many past papers do I need?” is the wrong question. How many past papers have you marked honestly? is the one that predicts grades.
The short answer
For Cambridge mark Cambridge past papers, | Weeks to exam | Rough target (per subject) | |---------------|----------------------------| | 12+ | 1–2 questions marked per week + topic drills | | 8–12 | 4–6 full papers marked, not just attempted | | 4–8 | 6–10 papers, heavy on weak components | | 2–4 | Quality over quantity — full papers under time + rewrite |
Doing fifteen papers without scheme marking is revision theatre. Doing six with line-by-line marking often moves marks more.
What counts as “one past paper”
A past paper only counts toward your total when you:
- Sat it under realistic timing (or a deliberate half-paper)
- Marked with the official mark scheme for that session
- Logged why each mark was lost
- Rewrote one weak part — not the whole paper again immediately
If you skip step 2, you are practising stamina, not exam performance.
By subject type
For Cambridge mark Cambridge past papers, - Prioritise recent sessions for your exact component list - One long question marked per study night beats skimming twelve papers - Track M marks lost separately from A marks
-
Full essays are slow — plan half the essays you think you need, but mark every paragraph against bands
-
Build a bank of evaluative sentences from examiner reports
-
Speed comes from pattern recognition — mark wrong options with a one-line reason, not just “B”
A simple 8-week counter (one subject)
For Cambridge mark Cambridge past papers, | Week | Papers / questions | |------|-------------------| | 1–2 | 4 structured questions, fully marked | | 3–4 | 2 half papers | | 5–6 | 2 full papers | | 7 | 1 full paper + 1 weak-component redo | | 8 | 1 timed paper + light topic review only |
Adjust up if you have more than eight weeks; adjust down if you are balancing four subjects — per-subject targets matter.
When to stop adding new papers
For Cambridge mark Cambridge past papers, stop increasing volume when:
- The same mistake type appears three times in your log
- You are marking generously because you are tired
- You have not read an examiner report for your syllabus in a month
Switch to fixing logged errors instead of downloading another PDF.
Use a second marking pass
Self-marking drifts generous. After your own pass, upload one question per session to [MarkScheme](/mark) for feedback tied to the real scheme — especially on questions you “thought were fine”.
Frequently asked questions
For Cambridge mark Cambridge past papers, use recent sessions first — command style and emphasis shift. Older papers are fine for topic drill once you know current conventions.
Yes, but only after marking and only the questions you lost marks on. Blind redo without marking teaches memory, not technique.
Rotate: one “heavy mark” night per subject per week beats one subject bingeing all papers in March.
IF YOU'RE STILL WONDERING
How strict should I be when I self-mark?
Stricter than feels comfortable: if the mark scheme allows two phrasings, your answer must match one. Log every lost mark before reading the scheme.
