I'm in y13 and my friend in a different college is also doing physics. I noticed last year that their work was so much easier so I began to use OCR A questions as practice before doing AQA cus they're so much easier to do and understand. You know what the mark scheme wants and get 3 marks for questions which would be 1 mark in AQA. Why is it so much harder (I'm predicted an A* in physics)
