Great to use as revision

Many people were mad these weren’t fully accurate but they are not meant to be the exactly real exam - that isn’t very easy to predict sometimes because exam writers change what they want to heavily focus on. Nevertheless, this is very useful to practice which is what people should use them for instead of just relying on them. The main issue was the fact that there weren’t many practical questions especially in paper 3 which is a main focus of paper 3 so that should be added next time. Thank you for this resource.
