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 also make it easy to practice. Carry a notebook and textbook on you. Waiting for a train? do a question. Appointment running late? question etc.
Don't rely on having the perfect conditions. Make sure you have a resilient strategy. If you have one window to study in a week and you can't do it that week you miss the whole week. That's bad!
