You’re going to have to find the best study habits are for you. I’m the strange person who rewrites their notes when they go home so they are neat. I also take notes from the text book and write it down within my neat notebooks… highlighting never worked for me.

For a test, I would study the neat version of class notes and textbook notes one or two times. I would also downsize the notes so I can carry it around with me to study while doing other things.

to be honest no smart people will ever claim to be smart because they know its not the right thing

but i would advice you make a schedule/time table

read the material as many time as u can and practice as much as u can

thats all u can do, and devote as much as time to your studies
