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.

I have happened across web sites with teaching demos for data structures and algorithms.  I had no reason to note them, so I have no list for you. Mainly it was when I looked into some teaching oriented language like Smalltalk Squeak or Logo. Some schools teach programming to young children, and they develop visual aids to explain stacks, linked lists, etc. For Uni level, various professors put their class notes online, but again I had no reason to note those sites. I was waitng for someone more recently out of school to answer you; they WOULD have reason to note those sites.

I glimpsed http://en.wikipedia.org/wiki/Linked_list and it has
links like http://cslibrary.stanford.edu/103/
