Passing exams with top marks means knowing what to write down, and what to leave out. You don't have to write down everything you remember and getting this right requires practice.
Before you start writing, read the number in brackets after each question. This tells you how many points each question is worth and gives you a clue to the length of the answer. For example, a three-point question means you'll have to write down three facts; a question with higher marks will always require more facts and a longer answer.
Some other clues found in exam questions are:
* the word 'define' means you have to explain each fact
* the word 'suggest' requires you to use your remembered knowledge to provide an idea
Once you have completed your practice exam you can check you answered the questions correctly by comparing your answers to the mark scheme downloaded from the exam board website.
