I would say focus on school the rest of this semester and get grades that can bump up that gpa even a tiny bit and show that you're most recent work is awesome. Also you need to think about how much time you'd study and if you think its realistic for your quant score to go up a significant amount in 21 days. My professors have told me that verbal and written are most important, and yours look good. However, I'd also think about the relevant work experience you have, letters of rec, your personal statement, and about the schools you are looking at. My biggest advice would be to expand the schools you're applying to. I'm not sure if you are applying to masters programs at the schools you listed or post-baccs, but for the masters programs, CU Boulder and U of the Pacific each get around 400 applications and only accept like 17%. They are super competitive schools that super students still get rejected from. If you're only applying to their post-baccs then ignore what I said. However, I'd still apply to more than four and look at how competitive they are. Use ASHA's edfind if you haven't http://www.asha.org/edfind/search.aspx !
