I'm sorry but NOONE should be allowed to fail Gym. If someone fails Gym, it's because their teacher doesn't like them.
Unless of course they went to a school like ours, were we ran a mile, then took a quiz on anotomy or general health etc. Silly, Gym is supposed to be for nothing but smaking or tossing a ball around eh!

Now, what they need is an option to play online games instead. THAT would be the proper release from the everyday schoolwork eh! I'd love to be that teacher. All the kids would do what I say and PLAY THEIR GAMES hehe.
