I use Isaac Physics regularly alongside the workbooks to provide problem solving practise for students. The boards below are made up of a mixture of the GCSE and A Level workbook questions with some of the more involved problems mixed in. There are also extension boards to provide practise for students who want to engage with problems beyond typical A Level standard.
It is well worth getting your students set up on Isaac Physics in class and getting them to complete some or all of the getting to grips with significant figures board before you start setting work for them to complete independently.
