Exercises, exercises and exercises. Go through the exercises available to you chapter by chapter. If you do not know the vocabulary used in the task, look it up. If you do, don’t. If you struggle with a task, skim over chapter and try to find something that might help you. If you have no clue how to solve the problem after some appropriate time spend thinking, look at the answer and identify the gap in your knowledge. Re-reading book chapters or lecture notes is for sure helpful during the semester, but this close to the exam, re-reading entire chapters is too inefficient — you spend time on recapping stuff you already know and might also feel a false sense of security because gaps in your knowledge aren’t as apparent when reading as opposed to doing exercises.
EDIT: Prioritise old exam questions from the same course (and the some professor), homework questions and questions from the text book if you have been working closely with it.
