WWU sucks, I'm a junior here right now. Waiting for my calc class as I type this actually.
Since you're already decided on coming here though all I can say is don't live on north campus, especially Mathes or Nash. I lived in hell aka Mathes but spent all my time, almost literally, on the ridge in Kappa with some friends up there (they had a 3 person room with only 2 of them, lucky me). Be prepared for the worst food you can imagine at the dining halls, be prepared to pay for lots of shit you don't want. Be prepared for tons of bullshit!
