No re gpa’s. Would have to do research on the UW site- you can do that just as easily as I can. If you are thinking of HS grades check admissions.
If you are trying to figure out college gpa’s I find that totally meaningless. Students take such a wide variety of courses, and at various degrees of difficulty within a subject, it doesn’t matter. Some may expand their horizons by taking courses in subjects they have little background or natural ability in and accept a lower grade than just doing things they can do easily. Some take many, others few classes… Too many variable and it doesn’t matter. You go to college to get out of it what you choose, not to have any gpa. Of course, those intending on graduate or professional schools will be able to do better than most college students, while taking more rigorous work loads.
No matter which college/U you attend you should figure they expect you to be successful. This does not mean a perfect gpa, especially as that depends on so many variables. You can expect to work harder than you did in HS. Along with finances you need to consider the academic fit of schools. Do you want to be that student who struggles but succeeds at a school, a student who only needs to study an average amount to do well or a student who wants to be at the top relative to others? btw- do not assume a lower tiered school will be a lot easier. It could be easier to fall into some bad habits and not study enough…
