Do you have any exam tips for Biology Paper 2?

So one thing I observed in my Biology class was that students would memorise every single piece of inforrmation about each biological process that was written on their 'comprehensive flashcards'. One thing they failed to prepare for was 'how to answer IB questions'. This was something I carefully examined and learned how to do by looking at various past papers mark schemes. One tip I have is that for the Part B section of paper 2, with the 8-mark questions, often you can get 1 easy mark by simply defining 1-2 of the terms in the question.
