stupid class

"Hey, I'm back to learn your stupid class about garbage!" Kristen Wiig on SNL. I bet every student has said this about a class sometime or another. I know i've said it about some of my classes like chemistry. Chemistry with Mr. demos is the worst thing ever because he doesn't teach us about anything so I think his class is a waste of my time and everyone else's. Every time I walk into his class room I just groan because he's an idiot. He doesn't have a teaching degree in chemistry. He majored in physics and thats not chemistry at all. When ever we take a test for him we have a review day but in that review day he teaches us something new that's going to be on the test. When the test day comes his wording of the questions throw everybody off. On the first test we took I answered a question that i remembered the book told us and he marked it wrong and he said he wanted his answer and not the books answer. Also we do tons of labs and he doesn't grade them fairly at all. I did a lab and i got a 75 on it then dustin took my lab and took some of the information and got a 85 and they were basically the same thing only his was worded a little bit differently.Mr Demos frustrates me and I'm always telling him on his tests that I hate chemistry with a passion and I'm only taking it because of college.
