Mark scheme and answers
Paper 5 consists of two questions (each carrying 15 marks) and the time duration of this paper is 1 hour and 15 minutes.
The examination paper does not require laboratory facilities.
The first question is the planning question, in which candidates are required to design an experimental investigation of a given problem, and answer the question with a labelled diagram and an extended piece of writing.
The second question is the analysis, conclusions and evaluation question, in which candidates are given an equation and some experimental data. From these they are required to determine the values for different constants. They are also required to estimate the uncertainties in their answers.
Some questions on this paper may be set in areas of Physics that are difficult to investigate experimentally in school laboratories, but no question requires prior knowledge of theory or equipment that is beyond the syllabus: candidates are given all the information that they need.
Note: Average score in this paper to secure A grade is 21 (out of 30).
