Exam questions by topic
These questions either cover topics from GCSE level or require you to think about how to solve, which is why they aren't under the relevant topic because that would be an indication of what to do.
Below are further example exam questions and their associted markschemes. These are from the equivalent additional maths exams set by different exam boards. The way the questions are framed may be slightly different from WJEC but the mathematics involved is exactly the same.
