What is the best way to revise?

A high grade in GCSE Biology requires you jumping through a few hoops. For certain questions, specific facts are required in the answer and certain structures are required for the answers. There isn't too much understanding invovled, more knowledge recall like in History. The best way to revise this is through doing past papers and then marking them yourself. This allows you to see what the markscheme is looking for and after awhile you will be able to spot signs of this in the exam paper. Aim to get through all the past papers before the exam and do about half of them without any help from books if you have the time.
