So we meet again - glad to see your doing physics too. Personally, i didnt even bother with questions from the textbook - mainly because were using Heinemann. What are you using? And I went straight to questions from checkpoints. And went well with them, but found that their wasnt enough and i need some more. So im planning on getting some more and just smashing out more questions, possibly doing some from past exams? Not sure. I wouldnt stress too much for physics in terms of holiday prep, maybe make some notes but the only things you really need for motion are the equations and what not, the real basics.
Edit: In terms of warming up the skills, i felt the same. Couldnt remember anything from last year. Just read over the textbook, highlight some of the key info and go from their. Maybe right them down, then just smash out questions and apply the knowledge.
