I am a student in college with a very good GPA and am a very good student. However, I go to a pretty lame school, and I seriously under estimated the science department and over estimated my degree of knowledge in chemstry. I am having a hard time understanding what is going on in class and what is being ask of me. I know it's mosly because I do not understand the lingo needed as a chemist. can any tell me a web site I can visit that can help me learn chemistry real quick even if is babyfied.

Just not so babyfied I being told what a test tube is! LOL

mainly I am having trouble with getting formulas mixed up with equations when asked to write them.

I get confused about isotopes

and generally what is expected of a Chemistry 101 student finishing this course with an (Well Earned) not given A!.
