Hi everyone, does anybody have some tips for OCR A A-level Chemistry and how to revise for it? I am very stressed as I recently got my mock results back and I have not done well for Chemistry at all.... I am hoping for an A however I will be happy with a B too. How do I improve?? I have been doing AS Level past papers so that I can excel at them before moving onto the A-level papers but even that is hard for me!! Agh what should I do????
