Not sure how long that school is but if your going to climb every day and have never climbed before, as weird as it sounds shave your legs from the calf down because all the hair is going to do is create friction and cause blisters. The only thing else I have to say is give it all you have and shine above and better than anyone in the class if you can and you will be greatly rewarded being top notch in the class! If you get a chance look up a union school you have to pay nothing and get paid to go to there climbing school. I did the college thing and can honestly say if I knew about the union apprenticeship I wouldn't even have paid my hard earned money to go to a school. But do what you want....
UNION TILL I DIE......
