Well, I'm about to start first year university for the second time! To not screw up this time, I'd like to be well prepared. So.. Do you guys have any links that would help me for university such as homework help links, etc?

Also I would really like to review my grade twelve stuff so does anyone have any good sites/PDFs* with reviews/books on grade twelve/first year chem/bio/physics/calculus/etc?

Any help would be appreciated.

try http://www.cramster.com
it has homework help on sciences and math

I used AP Review Books to refresh my memory on certain concepts the summer before college (Princeton Review, FWIW.)

Additionally, you stated that you will be starting college for the second time. If you do not mind me asking, why? If too personal, I have no problem talking via PM.
