Psychology

I really dislike psychology class, I am not going to say hate because I hate math class and I would take psychology over math any day. I just don't really understand what is going on in that class it is all so very confusing to me, and I don't know why. It is not like it is a boring class, I am not just doing to well in the class. I just don't do to well on the tests, its not like I don't study for the tests, because I do, but when I go to take the test I just sort of blank out, and then I forget answers to the test I should know, this is why I almost have a C in the class
