Self-Testing Strategies for Better Retention

Self-testing is one of the most reliably effective revision strategies available to students. Unlike rereading, it forces your memory to work — and that effort is what makes information stick long-term. This guide introduces five self-testing methods, from the simplest to the most sophisticated, so you can choose what fits your style.

Why self-testing beats rereading

When you reread your notes, the material looks familiar and your brain signals "I know this." But familiarity in reading is very different from the ability to produce information under exam conditions. Exams test recall, not recognition.

Self-testing creates the gap between knowing and not-quite-knowing, and forces you to bridge it. The Education Endowment Foundation rates retrieval practice — the technical term for self-testing — as one of the highest-impact, lowest-cost strategies available in education. It works because the act of retrieving information strengthens the memory trace in a way that passive review does not.

Strategy 1 — The brain dump

A brain dump is the simplest and most accessible self-testing method. After studying a topic:

Close all notes and set a five-to-ten-minute timer.

Write everything you can remember about the topic — definitions, examples, diagrams, processes.

Open your notes and compare.

Highlight anything you missed or got wrong.

The gap between your brain dump and your notes is your revision target. A brain dump done honestly takes courage — it reveals exactly what you do not know — which is precisely why it is so effective.

Strategy 2 — Cover, write, check

Cover-write-check is a structured self-testing technique that works particularly well for definitions, formulas, dates, and vocabulary:

Cover — hide the answer with your hand or a piece of paper.

Write — produce the answer from memory, without peeking.

Check — reveal the answer and compare.

Variation | When to use it
Cover the definition, write it | Key terms and vocabulary
Cover the formula, write it | Maths and science equations
Cover the answer, explain the process | Step-by-step procedures
Cover the date or name, write it | History and geography facts

Do not move on after a correct answer — give it one more attempt tomorrow. Do not skip an incorrect answer — that is the content your next session should prioritise.

Strategy 3 — Practice questions under timed conditions

Answering practice questions — without notes, within a time limit — is the closest simulation of exam conditions available during revision. It combines retrieval practice with time management training.

To use practice questions as self-testing:

Find a past paper or practice question for the topic you are revising.

Set the appropriate time limit (check the mark allocation for guidance).

Answer without any notes or resources.

Mark your own answer against the mark scheme.

Write down the marks you missed and why.

BBC Bitesize provides practice questions for KS3 and GCSE subjects that can be used this way after studying a topic.

Strategy 4 — The teach-back method

Explaining a topic aloud — to a family member, a friend, or even an imaginary student — is retrieval practice in its most demanding form. You cannot fake a coherent explanation: the gaps appear immediately.

After revising a topic:

Put your notes aside.

Explain the topic as if you were teaching it to someone who knows nothing about it.

Notice any point where your explanation breaks down or becomes vague.

Return to your notes and repair that specific gap.

The repair step is crucial. Teaching-back without checking what you missed is practice — but not learning.

Strategy 5 — Spaced self-testing over multiple days

The most powerful enhancement to any self-testing strategy is spacing — returning to the same material at increasing intervals. A single brain dump the day after studying produces modest gains. The same brain dump repeated on day one, day three, day seven, and day fourteen produces much stronger retention.

A simple spacing system:

Day 0 — study the topic and do a first brain dump.

Day 1 — test yourself again; focus on what you missed yesterday.

Day 4 — test yourself again without looking at day 1 results.

Day 10 — final check; only revisit what you still cannot recall.

This schedule means the most recent self-testing always happens just as the memory is starting to fade — which is the moment when retrieval practice is most effective.

Choosing which self-testing strategy to use

Strategy | Best for | Time required
Brain dump | Getting an honest picture of what you know | 10–15 minutes
Cover-write-check | Definitions, formulas, specific facts | 5–10 minutes
Practice questions | Exam technique and applied knowledge | 20–40 minutes
Teach-back | Conceptual understanding; identifying vague areas | 10–20 minutes
Spaced self-testing | Long-term retention across all topics | Ongoing

Frequently asked questions

How is self-testing different from doing practice questions?

Practice questions are one form of self-testing, but self-testing is broader. A brain dump, a cover-write-check exercise, or a teach-back session are all self-testing — they all involve producing information from memory without looking at a source. Practice questions add the dimension of exam format and time pressure. Both have value; using several methods across a revision period is more effective than relying on just one.

Does self-testing work for subjects like maths, where understanding matters more than memory?

Yes. Maths self-testing looks different from humanities self-testing — it involves attempting problems from memory, deriving approaches without looking at worked examples, and explaining your method aloud. The principle is the same: production from memory beats passive review. Doing five unseen practice problems without referencing notes is far more effective than rereading five worked solutions.

How many times should I self-test on the same topic?

As many times as it takes to produce a complete, accurate recall without looking at your notes. For most students, this takes three to five retrieval attempts spaced over one to two weeks. Once you can brain-dump a topic accurately and completely, you need only occasional light checks — perhaps once a fortnight — to maintain that knowledge.

What should I do with the gaps self-testing reveals?

Do not immediately reread your notes on those gaps. Instead, do a focused brain dump on just that gap, see what you can produce, then check. Targeted retrieval on a specific gap is more efficient than rereading a whole section. If the gap is conceptual — you do not understand something, not just recall it — then rereading or seeking an explanation is appropriate.
