College(?) boys vs College girls in various competitions.
 

Greetings all, any help would be greatly appreciated.

Things I remember:

Relatively older movie (definitely pre-2010s but probably older)

The boys group is mostly or all nerds/dorks no jocks.

One of the nerd group boys has history with the leader of the girls group

The girls group beats them in almost every competition.

I think one competition is a tennis match.

The final competition is a paintball game..

I think another group of boys (jocks I think) joins with high tech gear.

During the paintball game, one of the nerd group boys uses like a dart stick to shoot paintballs (like a spitball tube.)

That’s all I remember, any help would be greatly appreciated! I’ve been thinking about this movie on and off for years!
