As a high school athlete who aspires to attend college and win an athletic scholarship then you really only have two choices. you can attend an "elite sports training camp", you will get some instruction, but the main aim of these camps is to give you the chance to show your skills in a playing environment. A lot of coaches go to these camps because it gives them the chance to see a large number of top high school players in action at the same time. These camps can be expensive so do your research first, ask for a list of college coaches that are gong to attend. If you are interested in attending a specific university then email the coach, or better yet make a phone call, and let the coach know you will be at the camp. The College camp is your other option and I think the best, (If your parents can afford both then go for it), you have the coach, his staff and usually some current players in attendance.

Sports camps are fun but remember this: You need to be on your best behavior and be punctual. Coaches want to see how you conduct yourself off the field as well.
