Re-read all of my notes taken in class.

Maybe just spend some time at the end of each day reading my own notes. It won’t take too long and might be a good way to wind down and revise at the same time.
My notes aren’t the main thing to use when revising…

Once a week until the week before my exams and then perhaps one every two days the week before? Then each day before the exam of the subject until the exam and then switch subjects depending on what exam is next. Would be a good idea to do the same with my textbooks and also the college website and the websites I have bookmarked.
In other words slowly build up the amount of revision I do.
Remember there will also be revision done in class and homework(revising, I guess) to do.
