Answers for Students via Cramster.com

Cramster.com is a website that is very helpful to students. It is basically a solution guide to your textbook. Out of my physics and math classes,  I have found answers here. It shows you step by step how to do each problem without revealing the solution right away. Furthermore, Cramster offers answers to textbooks in these subjects: Students can review practice exams, walk each other through homework problems, share notes on the site while using the service. If you grab a free account you get the solution to odd problems. If you register to be a paid member you receive all the answers plus more benefits.
