Though these are not my favorite things in the world, they are a cool and helpful way to help me learn. Let me introduce you to OWL, my Organic Chemisty online "homework". These are online questions that my
organic chem. class uses to help us practice questions on what we are currently doing in class. We had to buy a subscription at the beginning of the year to use for the whole year. Though they are helpful, they are often lengthy and take a long time to do (aka NOT
FUN!!!). I am sure that there are other services that offer something similar to this, but I think that OWL is a good source to helpme study for tests in organic.
 Also, there are tutorials that you can do to help explain how different reactions work. Of course I would never recommend this to anybody who is not taking organic chemistry, do you really wanna know the chemical formula for a Malonic Ester Synthesis??? Yeah, didnt think so. BUT, I would say that if anybody plans on taking Organic Chem. or is currently taking it that it is a good way to help you practice for tests and quizzes. If you are interested in this,
you cannot actually see the format because it is a secure connection, but you can visit the websites above and read about what the service has to offer to its users.
