Definitions that you should LEARN for Unit 1
(you should be able to reproduce these definitions EXACTLY under exam conditions)
WHY do I need to learn them off by heart?
§ It is usually a good idea to define any terms used in the question at the beginning of your answer. If your definition isn’t accurate you won’t get any marks for it.
§ If you know PRECISELY what the terms in a question mean, you are far more likely to be able to give a top quality answer.
HOW can I learn these definitions?
Everybody has different ways of learning but here is a suggestion that is in three stages:
1. Cover up the terms side of the page and see if you can remember the terms that go with each definition. You can check your answers as you go by uncovering the terms one by one. Keep doing this until you can do it without any difficulty.
2. Cover up the definitions side of the page and see if you can recite the definitions accurately. Keep repeating this until you can do it without any difficulty.
3. Ask someone to give you terms randomly and check whether you can give the definitions.
(you may wish to make the above easier by starting off with only 10, or less, terms at a time)
