Trying out for college rodeo?

So there's three main events for girls in rodeo. Barrel racing, goat tying, and breakaway roping. When trying out for the college rodeo team, do I HAVE/NEED to be great at all three? I'm not gonna lie, I'm great at barrel racing and have an amazing horse. On the other hand I suck and goat tying and am all right in breakaway. So would they accept me for my skill in barrel racing and just train me in the other two, or are they looking for an all around member. Also, I could imagine it differs between schools and instructors right?
