Top 5 Tips

1. When revising, do not leave out any chapters because all exam questions are compulsory.

2. In the exam, all marks for answers to questions are awarded in multiples of three. For example, a question worth three marks requires you to give one item of information, while a question worth nine marks requires you to give three items of information.

3. Learn all the equations on the course. These equations carry important information and may be very useful to you in gaining marks.

4. Questions beginning with words like list or name require shorter answers than questions beginning with describe or outline which require more detailed answers.

5. Keep a dictionary of all the special words of physics, biology & chemistry and know what they mean.
