You can learn how to ski at Dartmouth and at the same time fulfill one of your 3 physical education requirements at the same time, I know that the cost is very reasonable and much less than the student rate of $20 (for a non-dartmouth college student) Rental $25 (non dartmouth students /employees)

I remember my daughter telling me that it was less than $300 if you wanted to take skiing winter term (she couldn't fit it in her schedule) The cost included transportation, lift tickets, rentals .
