I passed gym with like an A and I didn't do anything. nobody really did besides some black guys who always played basketball. so I just used the time to do homework. all I had to do to pass was change into gym shorts and do a few situps or whatever at the start of class each day
Is this really how P.E. works in America? That explains a lot of things.
Here in Norway we have organized workouts. You have to run the 3km under a certain time (idk remember exactly, but you have to run fast) to get a passing grade. You have to be reasonably good in basketball, soccer, volleyball and hockey, cause your performance in all those sports counts towards your grade. They even made us run the
multi-stage fitness test (which is hell, as everyone who has tried it will confirm). To get the best grade, you have to perform better than the Royal Marines (which I did :))
