I have produced a new set of free GCSE Maths quizzes on my Diagnostic Questions website. These quizzes have been designed to test the effectiveness of any GCSE intervention strategy. This might be after school classes, a series of revision lessons, or work with a tutor. The idea is that you assign the first quiz (the “Benchmark”) before the intervention, and then use the second quiz (the “Progress”) as a measure of the effectiveness. I hope you find them useful.
