 don't absorb too much information. When you're at university you'll have information flying at you from all different sides and angles. You've got lectures, tutorials, online videos, textbooks, your friends, anky cards, everything. What you want to make sure you do is that you select a couple of really good resources that are going to help you perform as best as you can on the exam. Stick to those and do those well. That way you get all the information you need without conflicting bits of information and advice from different places and you focus on what's important for your upcoming exams.
