lol at thinking you will be able to compete the 2nd year. unless you just an absolute phenom, you wont ever get good enough to compete at collegiate level if you didnt wrestle in HS.
if you go in there, i would definately have the attitude that its all about wrestling, not picking it up for future use. If you had never wrestled before and showed up to my school's wrestling practice talking about mma aspirations, you would have found yourself ducttaped in the shower with a chuck liddell poster shoved up your ass, swimming in a pool of tepid urine. not by me, mind you, but wrestlers overall are mean people.
if youre thinking it will be like your gym, it wont be. there were fistfights every week in our wrestling room. if you think JC wrestlers wont be that good, think again. most of the guys in there will have been the best guy on thier HS team, a few HS state champs, some take it serious, others not so much.
as for your eligibility, see my post here:
