good question....i would like to know also.
i've encountered that they are extremely strict about not using any money earned in YABA leagues/tournaments. if you use any of it for college, they may not let you bowl on the team if it's NCAA sanctioned. if you have used the money, the only way they will accept you is if you pay it back with your own money.
as far as i know, YABA holds your scholarship money for 6 years, so you could easily use it after graduating from college. however, they might change that number, and, if you've earned a good amount of money, you could get screwed
