Best colleges for horseback riding?

I'm going to be going to college in a few years. and yea. Horseback riding is very important to me. It has to be a very good riding program. The school has to be easy to get into. like a 70% or higher acceptance rate. Horses are very important to me and hope to compete internationally one day. I want to be the best but I do plan on getting my degree in international Business and equine science. I want to compete n grand prix level in the future and maybe go to the olympics one day. so please help me! thank you
