This is another important aspect of studying for tests and exams. You want to know exactly how you will be evaluated. Will there be essay questions? Is the whole exam multiple choice? Will there be computational questions? Is the exam mostly knowledge based or does it require analytical thinking? The style of questions being asked plays a big role in how you study for exams. If your exam was essay based, you wouldn't need to comb through your notes to remember every single fact because you would never be tested on them anyways. For essay exams, make sure you know the topics being tested on and then focus on collecting the main theories. What I like to do is for each topic, create a mini outline that essentially has all the main points regarding the topic. That way, you can reduce 20 or so pages of notes to maybe a 2-3 page cheat sheet that you can quickly view and memorize. If your exam is multiple choice or knowledge-based short answer, you want to focus on memorizing the material, which I call the soak method. All you need to do is review your lecture notes, making sure to SOAK in the material. You don't need to critically think about why a theory exists or its applications or arguments against the theory; you just need to know what the theory is. Multiple choice generally only tests you based on pure knowledge, so focus solely on memorization and nothing else. If your exam has computational questions (such as Math, Physics, etc.) then you would focus on doing practice questions similar to those you will be tested on. For these types of questions, just reviewing formulas and reading theory will NOT help you much. You need to be able to compute answers out on the test, and thus the best way to go about studying for these exams is to do similar practice questions. To summarize, make sure that how you're studying directly corresponds to how you will be evaluated.
