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.
