You make study notes for your own needs. Different students should have different study notes, tailored to the needs of each. I suggest you prepare your notes by topics. For each, write down materials/items that are likely to be important to the course; include solutions of special relevance. But leave out items/points you are already very familiar with, that are at the top of your head: there is no point including them as they will needlessly clutter your notes. You want a, say, 10-page summary of all those relevant material you cannot readily recall, rather than a 30-page summary that include material you are already very familiar with. For example, if you already know that sin^2x + cos^2x = 1, there's no point putting it in. You don't have the time in your final revision to go over a lengthy document. With the passage of time, as you become very well-versed in some of the material you have written down in your notes, you can delete these (or simply cross a single line over them). Remember, an overly lengthy set of notes may overwhelm you during your last panicky pressed-for-time revision.
One more thing: hand write your notes, rather than typing out. In writing out, you somehow "connect" the material with your memory; that's what I think, anyway.
