Flashcards
 
Some people like making and sorting flashcards.
They can be used in different ways. 
One possibility would be to use a separate card to write down each bit of information you need to learn. 
If you use quite small cards, you can carry them with you and glance at them whenever you have a spare moment.
  • E.g. on the bus; queuing in Asda etc.
 
Another use of flashcards:
When you need to learn a sequence of information, write each step on a separate card and practise putting them in the right order.  For example, this might be useful for different steps in an experiment.
