I've taken General Chemistry, 3 quarters, and been graded each time. I've taken Organic Chemistry, 2 quarters, and been graded each time. Yesterday I began Biochemistry. Today, I was given a quiz by my Biochemistry professor on everything I have ever or may have ever been taught in any of my previous chemistry courses. And I will be graded on this. Why? This professor should grade me on what he teaches me. Not on what others have supposed to have taught me. I'm pretty ticked off.
