Ask any teacher how to get an A* and they'll say "do past papers". But plenty of students do dozens of papers and see their grade barely move. The difference is not how many papers you do, but what you do after each one.
Stage 1: topical questions
As soon as you finish a topic, answer past paper questions on that topic only. Topical practice teaches you how examiners test each idea, the command words they use (state, describe, explain, calculate, suggest), and how much detail each mark needs.
Stage 2: full timed papers
Around three months before the exam, move to full papers under real conditions: timed, no notes, phone in another room. This trains the skills topical practice can't: timing, switching between topics, and staying accurate in the last 20 minutes.
The 5-step method for every paper
- Attempt the paper under exam conditions.
- Mark it strictly with the official mark scheme. Only award marks for points actually written down.
- Log every lost mark in a table: question, topic, and reason (didn't know it, misread the question, missing keyword, careless error, ran out of time).
- Fix the causes: re-learn the topic, practise more questions on it, or drill the missing keywords.
- Retest a week later with new questions on the same topics.
Why marks go missing
| Reason | What it looks like | How to fix it |
|---|---|---|
| Knowledge gap | Blank or wrong answer | Re-learn the topic, then do 10 topical questions |
| Missing keywords | Right idea, no marks | Learn mark scheme phrasing for common questions |
| Misread question | Answered a different question | Underline command words and units before writing |
| Careless error | Arithmetic, units, sig figs | Check every calculation line; show working |
| Timing | Last questions unanswered | Practise with a clock; set a minute-per-mark budget |
Don't save the newest papers
Keep the two most recent sessions aside for your final mocks. They reflect the current syllabus and question style most closely, so they give you the most honest prediction of your grade.
How our classes use past papers
Every course at PakTutorOnline includes topical worksheets, timed mocks and mark-scheme walkthroughs, and teachers track every student's mistake patterns. See how it works for your subject on our subjects page.
Frequently asked questions
01How many past papers should I do?
Quality beats quantity. For most subjects, 8–12 carefully marked full papers plus topical practice is enough, as long as you fix the mistakes from each one.
02Where can I find official past papers and mark schemes?
Cambridge International and Pearson Edexcel publish recent past papers, mark schemes and examiner reports for teachers and on their school support sites. Your school or tutor can share them.
03Should I read examiner reports?
Yes. Examiner reports explain the most common mistakes students made on each question, which is exactly what you need to avoid.
