ChemistryTop 5 Tips

1. When you receive your exam paper, spend a few minutes examining the content of the various questions. Decide fairly quickly which ones you can do best. Answer those questions first, but do not exceed the recommended 20 minutes per question limit.

2. Do not waste too much time trying to think of answers to particular parts of a question. Leave spaces and come back to these later.

3. If you are attempting question 4, it is a good idea to attempt all 11 parts. You will be marked on the best eight.

4. Remember to attempt all parts of all the other questions that you choose (except for questions 10 and 11, and questions on the Options).

5. It is very important to show the starting point and the various stages in every calculation, so that the examiner can follow what you are doing.
