From Module 2
The two best study techniques
You do not need ten different revision strategies. You need two. Both are backed by the strongest research evidence available.
Every revision session should involve you trying to remember without looking. If you are just reading or copying, you are wasting your limited time.
Three hours on one topic feels productive. You walk away certain you know it. That is the fluency illusion — familiarity, not learning (Bjork and Bjork, 2011). Research consistently finds that spaced practice produces substantially better retention than cramming the same total time — often around 50 to 80 per cent better, depending on the study (Cepeda et al., 2006). Spacing wins even in two weeks.
Five ways to use retrieval practice
Pick whichever methods suit your subject. The important thing is that you try to remember before checking.
How to space when you only have days
Ideal spacing uses gaps of days or weeks. But even with just a few days, you can make spacing work.
The rule: never revise the same topic twice in the same day. If you study family vocabulary this morning, study something different this afternoon. Come back to family vocabulary tomorrow.
A mini spacing plan
Notice how each topic appears on more than one day. Even a one-day gap forces your brain to work harder to retrieve, which strengthens the memory.
Classroom research found three spaced retrievals of the same topic is the sweet spot. Students who retrieved a topic three times across different days still remembered it nine months later. Aim to come back to each priority topic on at least three separate days before your exam.
Different subjects need different approaches
The principle is the same (retrieve from memory), but the best method varies by subject. Tap each one:
Do at least one timed past paper per subject
Before each exam, do at least one full past paper under exam conditions. Set a timer. No notes. No phone. Just you and the paper.
This does three things at once: it practises retrieval, it trains your time management and it shows you exactly where your gaps are.
Mark it using the mark scheme. For every mark you dropped, write down why you lost it. Did you not know the content? Did you run out of time? Did you misread the question? Each reason has a different fix.
Plan a revision session
Pick one subject from your priority list. Plan a 40-minute revision session (excluding full past papers, which take longer) using the techniques from this module.

What to take from this module
Two best techniques: retrieval practice (test yourself from memory) and spaced practice (spread topics across days).
Five retrieval methods: brain dumps, flashcards, past paper questions, teaching and cover-and-write.
Spacing in miniature: never revise the same topic twice in the same day. Even a one-day gap helps.
Different subjects, same principle: factual subjects use brain dumps and flashcards, problem-solving subjects use practice problems, essay subjects use timed plans, skills subjects need daily short bursts.
Timed past papers practise retrieval, train time management and reveal your gaps all at once.
Your first proper revision session
- Pick one subject and one topic from your priority list.
- Set a timer for 40 minutes.
- Start with a brain dump. Then do past paper questions. Then make flashcards for what you got wrong.
- Tomorrow, come back to the same topic and test yourself again without looking.
That is retrieval practice and spacing in action. You will feel the difference.
Next: Module 4 teaches you how to tackle exam questions. Command words, planning answers and what to do when you get stuck.
Retrieval practice
Roediger and Butler (2011) demonstrated that retrieval practice strengthens memory more than restudying. Karpicke and Blunt (2011) showed that retrieval practice produced 50% better recall than elaborative concept mapping one week later.
Spaced practice (the meta-analysis)
Cepeda, Pashler, Vul, Wixted and Rohrer (2006) is the canonical meta-analytic synthesis of distributed practice studies, finding that spacing produces substantially better long-term retention than massed practice. The follow-up paper Cepeda et al. (2008) showed that even short spacing gaps improve retention compared with massed study.
How many spaced retrievals
McDaniel, Agarwal, Huelser, McDermott and Roediger (2011) ran a classroom study with middle-school students and found three spaced opportunities to retrieve a topic was optimal for long-term retention, still measurable nine months later.
The fluency illusion
Bjork and Bjork (2011) describe "desirable difficulties" — conditions that feel harder during study but produce stronger long-term memories. The "fluency illusion" of cramming is a classic example: information becomes temporarily familiar, but recognition is not the same as recall.
