A-level physics examinations contain questions in which practical skills are assessed away from the laboratory. At least 15% of the marks on A-level papers address practical skills and the usual tally is higher. These questions can address aspects of planning, such as decisions on procedures and graphical methods, uncertainty analysis and the application of advanced mathematical techniques.
In common with other awarding bodies, WJEC (in Wales) and Eduqas (in England) expect A-level students to use both logarithms and error bars in their experimental work. According to the specifications students are not normally expected to apply the two in the same question. However, question 5 from the summer 2022 WJEC Unit 3 paper gives enough information in the scaffolding of the question to allow students to engage in this kind of analysis.
