The seniors in my high school are always yelling at the sophomore class because we screw around at track practice and in school, though we r better then them in track so they really have to right to yell at us?

Respect... you will understand this when you are seniors. And by the time you are out of school for a year you wonder why you even worried about it... seriously.

It may seem like a big deal now... but a year after you graduate you will realize its all kids play. So try not to take it all too seriously... in the big scheme of life... this is insignificant.
