A flash card is simply a small piece of card which a fact, concept or idea can be written on. Many students find flash cards a particularly helpful way to revise.
1. Invest in some index cards, or cut some pieces of card into A6 sizes.
2. When revising, if you find a fact or concept that you summarised earlier particularly difficult, write it down on one of your flash cards. You can then keep these in your pocket or bag and get them out for a quick read whenever you have a few minutes spare, on the bus, in a queue etc.
3.You can even ask family of friend to test you on these.
