SPM tips: Physics Paper 3

In paper 3, you are given with1hour 30 minutes. There are 2 section A & B.

In Section A:

1. consists of two structured questions and must answer both of the questions.

2. The total marks for this section is 28 marks. You are advised to spend 60 minutes on this section.

3. The questions in this section are based on experiments that you should have done in the lab.

4. The questions in this section normally require you to collect and tabulate the data in a table and to plot a graph.

5. You are normally required to state the manipulated variable, the responding variable and the fixed variable based on the aim and the procedure of the experiment. Make sure you know the meaning of each of the variables stated above.

6. The questions from this section also involve the interpretation of graphs. As such you will need to carefully determine the quantity represented by the gradient of the graph provided. You will also need to know how to determine the gradient of the graph.U must know the physical qty represented by the gradient.

7. The questions from this section may also involve the calculation of certain quantities. Make sure that you write down all the steps involved in the spaces provided in the question paper.

8. Dont forget to state units & please improve your maths skills on straight line & curved graph.

9. U must also know how to relate the graph, either a directly or inversely proportional type.

In Section B:

1. Section B consists of two questions and you must answer one question only.

2. The total marks for this section is 12 marks. You are advised to spend 30 minutes on this section.

3. U are normally given with a diagram of a situation in our daily lives together with a brief write-up on the situation shown.

4. You will have to study the situation carefully as you are normally asked to state one suitable inference/hypothesis that can made from the situation. Then u'll be asked to design a suitable experiment

5. Make sure you provide a fully labeled diagram of the apparatus used. Write out your experiment in passive form and use short sentences.

6. When making a conclusion, make sure that your conclusion is in line with your hypothesis.
