I'm in University Physics I - Mechanics and Heat. The exam had six problems, and I made stupid, careless mistakes on 3 and ended up with an 85. I should have had an A. It was over probably the easiest subject matter of the course: Math Review, Velocity and Acceleration, and Vectors. I'm frickin' ticked off with myself. I don't want to be a B-making physics major. I'll quit or switch to an "easier" degree.
