A friend of my golfed div 1 in college. And he rarely plays now 10 years out of school, wife, kids, and work prevent him from playing much, but he still shoots low 70's to mid 60's on our local course. Now he has been in some big tournaments and played against some of the best in the world. And as he says in his hay day he would be breaking 60 on our local course. Your best bet practice the short game and concentrate on hitting fairways. Find a PGA level course when you are consistently shooting par, and give it a go and see how it affects your score. Place well in your high school state tournament and you should get some scholarship offers.
