How to memorise maths formulas (and which ones you don't need to)

Most students spend memorisation effort on formulas that are printed in the booklet and skip the ones that are not. Start by sorting them.

By Joseph Eno ·

Both GCSE and A-Level Maths provide a formulae sheet, and both expect a set of results to be known from memory. The exact split is published in your board's specification, so the first job is to print the sheet you will be given and mark up everything that is not on it.

Sort before you learn

Three categories, three treatments
CategoryExample typeHow to handle it
Given in the examMany standard results printed on the sheetLearn where to find it, not the text
Must be knownResults your specification lists as requiredDaily blank-page recall
DerivableResults you can rebuild in thirty secondsPractise the derivation, not the string

The method that actually works

  1. Write the list of must-know results on one page. One page only — if it does not fit, you are including given formulas.
  2. Every day, from blank paper, write out as many as you can in five minutes. No looking first.
  3. Mark it. Circle the ones you missed or wrote wrongly.
  4. Only revisit the circled ones during the day, then repeat the full blank test tomorrow.
  5. Once a week, write them out and immediately use each one in a single question.

Tie each formula to a trigger

A formula you can write but cannot deploy is only half learned. For each one, note in three words when it applies — 'right angle, no hypotenuse', 'rate of change', 'area under curve'. In the exam you retrieve by trigger, not by alphabetical order.

Derive rather than memorise where you can

Several standard results follow from one another in a couple of lines. Learning that route is more robust than learning the string, because a derivation you understand can be rebuilt when your memory is under pressure, and it usually earns method marks along the way.
