There are two ways you may approach this:
1) contact the schools that your mom has in mind and talk to the coaches and ask if they have a camp or can you come to the school for a tryout. The coach may help you with other options.
2)Tell your mom that with the cost of a 4 year college, you can get most of the classes that you will need for the first 2 years at the J.C. for thousands of dollars less and the chance of going to a 4 year college from that point may be able to pick up scholarship to help offset the cost for your 4 year degree.
We went the J.C. route and my son received three very good offers from some very good schools. Unfortunely, we were unable to accept them, but that's a different story.
Good luck whichever route you take and enjoy your college life.
