Flashcards are one of the most effective revision tools for IGCSE Physics, but only if they are made and used correctly.
Why flashcards work for Physics
Physics exams test recall of:
- Definitions (worth 1 to 2 marks each, 8 to 12 marks per paper)
- Equations (needed for every calculation question)
- Key facts (properties of radiation, EM spectrum order, circuit rules)
Flashcards use active recall (trying to remember before checking) and spaced repetition (reviewing at increasing intervals). Both are proven to improve long-term memory.
What to put on flashcards
Type 1: Definition cards
Front: “Define specific heat capacity.” Back: “The energy required to raise the temperature of 1 kg of a substance by 1 degree C (or 1 K).”
Type 2: Equation cards
Front: “Write the equation for kinetic energy.” Back: “KE = 0.5 x m x v^2, where m = mass (kg), v = speed (m/s), KE = kinetic energy (J)“
Type 3: Concept cards
Front: “Why does a transformer only work with alternating current?” Back: “A changing current in the primary coil produces a changing magnetic field, which induces an e.m.f. in the secondary coil. A direct current produces a constant magnetic field, which does not induce an e.m.f.”
Type 4: Comparison cards
Front: “Compare alpha and beta radiation (3 differences).” Back: “Alpha: helium nucleus, charge +2, stopped by paper. Beta: electron, charge -1, stopped by aluminium. Alpha is more ionising; beta is more penetrating.”
How to use flashcards effectively
The Leitner system
Sort your cards into three boxes:
Box 1 (daily): Cards you got wrong or are new. Box 2 (every 3 days): Cards you got right once. Box 3 (weekly): Cards you have got right multiple times.
When you get a card right, it moves to the next box. When you get it wrong, it goes back to Box 1.
Session structure
- Start with Box 1 (5 to 10 minutes).
- Move to Box 2 if it is a review day (5 minutes).
- Move to Box 3 if it is a weekly review (5 minutes).
Rules
- Always try to answer BEFORE flipping the card.
- Say the answer out loud or write it down. Do not just think it.
- Be honest. If you “sort of” knew it, the card stays in the current box.
How many flashcards do you need?
For the full IGCSE Physics syllabus:
- About 50 definition cards
- About 30 equation cards
- About 40 concept/comparison cards
- Total: approximately 120 cards
This sounds like a lot, but you make them gradually as you study each topic, not all at once.
Common flashcard mistakes
- Too much text on one card. Each card should test ONE piece of knowledge.
- Making cards but never reviewing them. The review is what produces learning, not the making.
- Only reviewing the easy cards. Spend more time on Box 1 (your weakest cards).
- Copying from the textbook without understanding. If you do not understand what is on the card, you cannot recall it.
