Where can one find free study guides online?

There are many helpful websites that can be found through google which will take the student to the study aid needed. For example, the website Novel Guide contains 'Test Prep Material', 'Reports and Essays' and even 'Videos'. This website allows the student to join for free for access to study guides, literature criticisms and access to the essay and report database. The student must pay a fee if they would like to use more content, for example, help with homework.
