Past Papers vs Notes: Which Predicts Your Score Better

The Practice Paradox

Ask 100 students how they'll prepare for finals. ~70 will say "I'll re-read my notes." ~20 will mention flashcards. ~10 will mention past papers.

The ranking should be inverted. Past papers > flashcards > re-reading notes.

Why past papers win

1. Format match — your brain rehearses the exact cognitive load of the real exam.
2. Distribution match — past papers reveal which topics actually appear (and which never have).
3. Diagnostic — every wrong answer maps to a specific gap.
4. Stamina — a 3-hour exam is a stamina event. Past papers train it. Note-reading doesn't.

How to actually run a past paper

1. Print it. Phone away. Timer set.
2. Sit at a desk, not in bed.
3. Write under exam conditions — no skipping back, no "I'll come back to this".
4. After: mark honestly, ideally before looking at the mark scheme.
5. For every miss, write why — "didn't know the formula", "misread the question", "ran out of time".

What to do with the misses

Group them. Conceptual gaps go on your study list. Time-management losses go on your strategy list (e.g. "skip 3-mark questions if I'm 5 min behind on essays").

How many is enough?

Five timed past papers, fully marked, > 30 hours of re-reading. If you have access to fewer than five, redo old ones — your blind spots will surface differently each time.

Notes still matter — for one thing

After the past paper diagnoses your gap, your notes (or textbook) fix it. Notes are the intervention, past papers are the diagnosis. Most students do them in the wrong order.

The bottom line

Notes feel productive. Past papers expose what's actually missing. The student who does five timed papers and patches gaps will outscore the student who reads notes for double the hours, every time.
