I love this, it is the largest test bank on the web for organic chemistry exams.  It is completely free and is a great way to study for your exams.  Testbank is located at organic chemistry, scroll to the middle of the page and click on “practice exams”.  There are over 50 practice tests from Organic I and Organic II, most with the correct answers.  See former exams from universities around the country. 

Good luck and happy reacting.
