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.

You don't get into programming by taking classes, just like you don't get into auto mechanics by taking classes.  You get into those by tinkering with them in your spare time, building hobby projects, and forming your own practical understanding.  Then you can enter academia and grow your knowledge.
