method to study,

hi, i want to know what´s your method to study (especially on college) any kind of subject. i have a final oral exam i have to do next monday and i´m kinda stuck on a topic my brain doesn´t seem to want to learn.

what i normally do is make summaries, read them and then i make concept maps with important keys concepts i have to remember. it works out for me, but there´s times where there´s too much information and i get lost (not knowing what to summarize- what to ignore, what to pay attention to)

also, i want to know if there´s any kind of helpful platform for students. sometimes i use notebooklm but lately it hasn´t been helping me much.
