Help a college student

/prog/ I don't understand data structures very well and I have a test next week that will either make me or break me. I am usually a star student but something about me/data structures/teacher isn't right. I pay attention in class and take pages and pages of notes and every night I read the related material for at least 1-2.5 hours each and every night although I still find myself lost. Please give me advice on how I can better understand this subject.

there are no tricks and no secret formulas. hell, no silver bullet. no vampires either.

just practice and reading. having someone to guide you and telling you what you're doing wrong also help.
Also, read sicp (not trolling btw)
