Wait-listed, chances on getting in? (In need of wisdom)

Hello, I received my response from the University of Washington Seattle today and they have me currently wait-listed. I’d like to explain where I’m at and hear from you to know what my chances of getting in are for this year.
I am a full IB student with a GPA of 3.4 but lived in Europe for 14 years and am fluent in English, French and German. From the paper, it appears that they focus on my senior year first semester grades. I am presuming this is good because during first semester I got straight "A"s.

What do you think are my chances of being accepted to UW Seattle this year (2015)?

I think I read somewhere that last year there were 754 people on the waitlist and 704 ended up being accepted. Don’t hold me to that though it was a stat from the Unofficial Transcript thread.

That was in 2013. I believe the 2014 one was much lower, but it changes year to year so you never know.

Anyone know the typical amount of in state applicants that get waitlisted?
