What could be my chances in Udub, Seattle acceptance?

Hi everyone,
I have a SAT score of 1500 (yeah it’s bad), but a 3.8 GPA and a running start student, with excellent GPA in it too, taking English, Math, Chemistry, Biology, Polictical Science and Art. Plus a member of honor society in both collage and school. What could be my chance of getting in University of Washington Seattle? Please help if you have any knowledge about it.
Thanks
