As much as i used to hate PE i do think its a good idea to do it. I think it would be better if you got to choose what you do however. In years 7-9 we had no choice and it was a nightmare leading to bullying because i couldnt run properly in athletics or couldnt even do a forward roll in gymnastics. Then for year 10 and 11 we got to choose what we did and what do you know, i got teh highest grade in tramopolining (SP?) and made the netball team. Doing something you like makes it more appealing and your less likley to worry about failing.
