for more context: i have to take an exam in 6 months or so. this exam covers around 16 college courses (mostly math and computer science related), has around 120 4-choice questions and 4 hour time to answer, so a little over 2 minutes per question. the questions are around half split between problem solving and memorizing.
for a few of the subjects i probably already know most of their content, and a couple i couldn't understand from the start but the majority of them were ones that i've studied at some point but have forgotten now.
so my question is how the hell can i prepare myself as best as i can in the little time i got? what i need are some resources to help me plan my study sessions and how i would go about studying, and also how to take mock exams from myself. any other tip is also appreciated.
2 or 3 sessions a week. Not longer than 2 hours. Habits are easier to form earlier in the day.
Take the time you have, take 2 weeks off the end, in the remainder of time divide each session according to how far along it is and spend the elapsed time % on revision. Obviously don't be pathological, one minute of revision is useless. Like at 3 months in 50% new stuff 50% revision.
Don't revise by just rereading stuff, pick problems to do in samples of topics already selected, or practice exams etc. Old uni profs might send you some practice exams and stuff if asked.
