Grad School Blues

My teacher is an asshat wrapped in a douche bag. 5 hours of my life vanished and I still get to lose 2o points. I should have just blown the assignment off.
Why would you write an entire chapter on solving a series of equations using a specific method, then have the very first assignment be to solve those equations using a different method. A method, by the way, that is described as cumbersome and complicated in the textbook, and only explained as a method that will be assigned at the end of the chapter.
Way to force me into re-inventing the wheel in a pre-determined inferior method. Good job guy, you have successfully made me want to quit school and burn all my textbooks on top of your desk. That is a unique feat. There should be an XBOX achievement for that.
