If you're looking for a refund or class credit, you need to back out of the class a full week before it starts. (No exceptions!) We know it's draconian, but since we aren't charging an arm and a leg and have to buy all our materials in advance, it's kinda hard to deal with last-minute bailings.
We also can't transfer registrations to a future session of the class. Sorry!
Instead of dropping out if you have a schedule conflict, a better idea is to ask around and see if any of your friends want the spot. We can't give you a refund less than a week out, even if there's a wait list for the class.
Regarding bad weather, we generally only cancel classes if the subway system stops running. If traveling during snowstorms might be an issue for you, please take this into account before registering for a class.
