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.
Oh yeah also when marking your own stuff you have to be harsh. Mostly right is entirely wrong, do it again till it's right etc.
Sucks but you don't want to accidentally learn bad habits
yep. i mean you can guess on the exam itself since it's multiple choice if you eliminate some choices statistically it's the more logical choice but when practicing as you said you gotta mark yourself very harshly.
