Understanding how to approach exam questions helps to boost exam performance. Questions will include multiple choice, descriptions and explanations, using mathematical skills, and extended writing.
Some questions in the exam will require you to recall and apply equations you have learned in class.
Other questions will ask you to use the 'Physics Equation Sheet'. This is a set list of equations given to you in the exam. In this case you should find the correct equation and apply it in your working.
Make sure you read the question carefully so you understand what you are being asked to do. If an equation is given then use it, it's not a trick.
