Revision that works when nothing else has

Ask a pupil how revision went and the honest answer is often “I read over my notes for two hours.” Ask what they can now do that they could not do before, and the answer is usually silence.

Re-reading is the most popular revision method and one of the weakest. It feels productive because the material becomes familiar, and familiarity feels like knowing. It is not the same thing. Recognising a worked example on a page is a long way from producing it on a blank one under exam conditions.

Test yourself instead of reading

The single most useful change is to close the book and try to produce the material from memory. Attempt the question before looking at the solution. Write out the derivation without the notes. Say the definition aloud before checking it.

This is harder, which is the point. The effort of retrieval is what builds the memory. Reading is comfortable, and comfort is a poor signal of learning.

A practical version for Maths and Physics:

• Work the problem cold, without the worked example beside you.
• Only when you are stuck, and genuinely stuck rather than two seconds in, look at the first line of the solution, then cover it again.
• Redo the same problem from scratch the next day.

Spread it out

Four hours of Physics on a Sunday is worse than four sessions of one hour across the week, even though the total is identical. Leaving a gap between sessions forces retrieval to work harder each time, and material revisited after a gap sticks better than material hammered in one sitting.

This is also why starting in April does not work for a May exam. Not because there is too little time, but because there are too few gaps left.

Mix the topics up

Revising one topic per session, in order, lets pupils get through the whole thing without ever having to decide which method a question needs. Then the exam asks a question that could be about three topics and does not say which.

Mixing topics inside a session is uncomfortable and feels less fluent. It also trains the decision the exam actually tests.

A week that holds up

A workable revision week for one subject looks less impressive than most revision timetables and works better:

Forty minutes, five days, one subject. It beats a four-hour Sunday, and it survives contact with a normal week.

The one thing to stop doing

Stop making new notes. Copying out material that already exists in a textbook feels like work and produces a tidier version of something you already had. If the notes are already there, use the time on questions instead.

If a pupil has been revising for weeks and their marks have not moved, this is almost always why.
