In NCAA Div. 1 you start a clock on your 5 years of eligibility as soon as you enroll full time in college. You can choose to sit out as many of those years as you like, but you only get 5 from the time you first enrolled. I believe D2's and D3's are the same but I may be wrong. If you are going to be in your third year next year, you would have 3 years of eligibility. There are exceptions to eligibility issues, but that is the standard as I understand it.
