Revision for Politics and International Relations.

Just posting this on here because I was curious as to how other people revise for this particular degree. I'm in my 2nd year studying Politics with International Relations at Lancaster University, and I have 4 year exams coming up in May and June. Whenever it comes to exams for this degree I tend to just find myself reading a hell of a lot from the reading list we were given at the start of the year; not really writing any additional notes or information down to help with revision. I was wondering how other people studying the same or similar course do for their revision. I have friends doing subjects such as Biology and Physics that follow much different revision routines, but that's pretty much to be expected seeing as they are completely different subjects. I've found that with my modules there is a hell of a lot of crossover, and a lot of the information and such that we have learned and discussed along the way has been consolidated in my mind pretty well, meaning I don't feel the need to write down copious amounts of additional information in order to revise effectively. Any other opinions on the matter?

Second year here, and I struggle with revising too. I make spider diagrams based on the lectures, then look at all the past questions I can find and answer them. Then I make notes and look up things I found hard in the past questions. I don't do well in exams though, usually only about 59, give or take.
