I know that the exam is still pretty far off, but it’s never too early to prepare!
During the written part of the exam, you will have roughly 12 questions which weigh 80 marks in total. Which means each question will average around 7 marks. So it would seem wise to concentrate on heavily-weighted questions (eg 8-10 marks each) because the questions in the exam would probably be a half heavily-weighted and the other half 2-3 marks each. Keep that in mind when you study.
A popular heavily weighted questions is Davidovsky’s definition of inflammation (2nd Colloq).
