The problem with PE is that it can be very inconsistient when it comes to grades. My PE teacher, this year, graded us in our Bowling unit (I'm in "Life Sports" where we do bowling and billiards and whatnot) like this. He bowled a game, and got 150. If we got a 140, we got 100 percent, 130 a 90 percent, and so on. I bowled a 70 and almost failed the class. My teacher last year graded us in our basketball unit based on how hard we tried to get the ball in the basket (ie, if we tried to do all the moves).
