Past Papers vs Notes: What Actually Predicts Your Score

If you walked into a classroom of A-grade students and a classroom of D-grade students one week before the exam, you would see the same difference every time: A-grade students are doing past papers. D-grade students are still making notes.

Why notes feel safer

Notes are comfortable. You are in control. Nothing tells you that you are wrong. Past papers, by contrast, are humiliating — they expose every gap immediately. That discomfort is exactly what makes them so effective.

The 80/20 of revision

For most exams, the optimal mix in the final two weeks is roughly:

• 80% past papers — including marking, error analysis, and re-doing wrong sections.
• 20% targeted notes — only on topics where past papers showed real weakness.

If you are still spending 80% of your time making notes, your score is being capped by your method, not your effort.

How to extract maximum value from one paper

Most students "do" a past paper, look at the score, and move on. That is roughly 20% of the value. The other 80% is in the analysis:

• Group every wrong answer by type: knowledge gap, misread question, careless error, time pressure.
• For knowledge gaps — make one flashcard per gap.
• For careless errors — note the trigger ("rushed final 5 minutes", "skipped showing working").
• Re-do the wrong questions cold three days later.

The mark scheme is the syllabus

Examiners write the mark scheme before the test. The mark scheme tells you, almost word for word, which phrases score points. Read three mark schemes side by side — you will see the same accepted phrases reappear. Learn those phrases verbatim.

When a tutor is worth it

If you have done three past papers and still cannot push past a certain band, a tutor can usually pinpoint the bottleneck within the first 15 minutes. They have seen the same exam hundreds of times.

You can browse tutors by exam board and subject, or explore subjects to find one who specifically tutors your syllabus.

The takeaway

Notes feel productive. Past papers are productive. Flip your ratio in the final two weeks and watch your mock scores climb — usually within 7–10 days.
