The basic idea is to summarise information to be learnt.
Using Word, create a text box about half the page and start typing…
Use bullet points
Use bold for key words
Don’t put too much information on each card
Save them on your computer carefully—so that they can easily be referenced.
Print them out onto card, cut into A5 size
Later, print new copies but perhaps miss out key words/formulae etc for you to use as a test.
