I never get finished. The questions were all on trivial details. This method involves some time planning but is far more effective than cramming all your review into a few days or even hours before the exam. Begin each study session with a quick review of any material you've studied previously, so that this previous material stays fresh even if you studied it in detail several weeks before the exam. Weekly review of material right from the beginning of the semester can drastically reduce the amount of time you'll need to spend relearning old material before the exam.
Some students advocate an emphasis on factual detail, terms and definitions.
They memorize as much material as possible, and make note of small but interesting details. Other students concentrate on understanding the ideas and concepts in the course which knit the facts and details together. They emphasize the similarities and differences between concepts when studying. Since most exams test the recall of facts and definitions and an understanding of concepts, the approach you take to studying for multiple choice tests must be based on a thoughtful analysis of the requirements of the particular course you're taking and the approach of your instructor. You'll be better prepared for major exams if you look at each small test during the semester as an indication of not only how much of the course material you know, but of the type of knowledge you have as well.
