I've been in this situation. The only thing you can do is educate them on freeskiing. Here's how you do that:
Every day, come in dressed in your park attire. Nothing less than xxl is acceptable, unless you're taller than 5'8, then everything must be xxxxl. Remember to where your full tilts, because no-one likes shin bang and math class together.
Change your vocabulary. Every other word you say is now 'dope' or 'sick'. If your teacher writes something that you actually understand, say 'whaaaaaaaaaaaaaattttttttttt'. Extra emphasis on the 'aaaaaaaaaaaaa' bit, and remember to increase the pitch of your voice while saying it.

Ask your geography teacher 'How do you get to Chad's gap from the bottom of Alta".
Follow these simple steps to educate everyone on how 'based' skiers are, you'll see them flooding to the hill in a matter of weeks.
One day I might write a self help book.
