Here's the system I developed to enable me to excel in medical school... but the system would work well for any level of study.
Let's take my Cardiology course, for example, which had a midterm and a final. Once I got a syllabus with all of the topics which would be covered for the exam, I would make up a "Track Sheet" which would have all of those topics for the upcoming exam listed in the order they would be given in class. My sheet would also have little boxes next to each topic which I would bubble in each time I reviewed a particular topic. At the start of the Cardiology course, my track sheet would look something like this:
CARDIOLOGY - MIDTERM TRACK SHEET
Cardio Pathology I [ ] [ ] [ ] [ ] [ ]
Heart Failure [ ] [ ] [ ] [ ] [ ]
Cardio Pharm I [ ] [ ] [ ] [ ] [ ]
Cardiac Arrhythmias [ ] [ ] [ ] [ ] [ ]
Cardio Pathology II [ ] [ ] [ ] [ ] [ ]
Cardio Pharm II [ ] [ ] [ ] [ ] [ ]
Valvular Disease [ ] [ ] [ ] [ ] [ ]
Cardio Pathology III [ ] [ ] [ ] [ ] [ ]
Cardio Pharm III [ ] [ ] [ ] [ ] [ ]
.
. (and so on, for about 60-70 lectures)
.
Then, each time I would review a particular lecture I would bubble in one of the boxes. Like:
CARDIOLOGY - MIDTERM TRACK SHEET
Cardio Pathology I [X] [X] [X] [ ] [ ]
Heart Failure [X] [X] [X] [ ] [ ]
Cardio Pharm I [X] [X] [ ] [ ] [ ]
Cardiac Arrhythmias [X] [ ] [ ] [ ] [ ]
Cardio Pathology II [ ] [ ] [ ] [ ] [ ]
Cardio Pharm II [ ] [ ] [ ] [ ] [ ]
Valvular Disease [ ] [ ] [ ] [ ] [ ]
Cardio Pathology III [ ] [ ] [ ] [ ] [ ]
Cardio Pharm III [ ] [ ] [ ] [ ] [ ]
.
. (and so on, for about 60 lectures)
.
My goal would be to review each lecture five times before the test. Usually, my first pass was a quick "read only" review, meaning that I would not highlight or draw anything on the notes. The next pass I'd highlight, the third I would write in, and by the end I was attaching post-it notes to my pages which would emphasize material I thought I would have difficulty recalling. People would often comment on how "digested" my notes were.
The benefit of this system is that you can monitor your studying such that you give equal attention to ALL areas of the exam. How many times have you gone into an exam only to be asked a question and you think to yourself "Shoot! I didn't study that section enough!" This system helps you avoid that. It also helps you to keep your studying interesting because you can skip around and study things in different orders, without the risk of missing important material. I can think of nothing more boring than sitting down and reading a pile of notes from start to finish. Skip around, make it interesting -- but keep it balanced!!
Again, this worked great for medical school. But variances of this system would work for premedical courses as well.
Hope this helps.
