If you are in Business school or a pie major like pschology, English, etc and are decently smart, then yes, if you schedule very efficiently. Also, you need to be able to ride hard all day and still be able to do schoolwork at night, and compromises will be made llike social life extracurricular involvement etc.
I assuming your parents are going to be paying for everything, because I doubt you can be a full-time student, ski 5 days a week and hold a job enough hours a week to support yourself, just doesn't appear to be enough hours in the day, although I am sure there are people who are doing that.
In my experience, I have only been able to ski 3 days or 4 a week at most without grades being affected. But, I personally am not good at skiing all day and being able to stay awake all night and do homework, I work much better in the mornings when I am fresh. I personally think that if all you care about is skiing, you should just ski and work, and do college later when you will actually apply yourself. If you try to do the ski 5 days a week, and do full time classes either you aren't going to live up to the full potential of your skiing, and you will be dissapointed, or your grades will be sub-par and you will be dissapointed.
Or just come here knowing you are going to get a nice education, be surrounded with hot women, and get to ski a fair amount and just be happy.
