So I’m currently on the waitlist for my #1 top choice, but guess I should start looking for housing in case things don’t pan out how I’d like them to. Is it normal to find roommates and start planning ahead for housing even though there’s a (hopefully good) chance I may not actually end up going to that school? What’s the etiquette involved in this sort of thing, in terms of giving a heads-up notification and actually going through with signing a lease, etc.?
