I agree with the above poster. Many folks want to get fancy and forget the basics. REPETITION. Many focus on the objectives thinking answering the objective will get them by. Thats fine, it might, but that will get you passing at best.
Here is what works for me.
1. Go to SELECTIVE lectures (some profs are not good, some )
2. First pass in lecture or at home listening, listen to the theme, what is going on?
3. Get another pass the same night, annotating the slides, and write in simple words (ok this slide is talking about what)
4. Friday night into Saturday night get another pass of it, adding more details, using resources like sketchy, pathoma, BRS
5. Sunday, memorize, and use the dry erase board for minute details.....
There, you got 4 passes in a week and then before exams roll get 1 to 2 passes again. One thing I recommend that makes the difference for me in making a A vs a B, is listening to the lecture AGAIN. Youll be amazed what you can pick up on once you have learnt it yourself.
I know time is limited at times, with labs, and and living your life, but stick to the basics honestly of reading the material over a few times. If you cant explain it to your mama, then aint no chance you understand it well enough.
