You are looking at schools that are reaches for your stats in general. Applying to Computer Science adds an additional layer of competitiveness. Not to be a Negative Nellie, but I very sincerely doubt that you’re going to end up choosing between Georgia Tech and a UC. Plus, you’re looking for “as cheap as possible” and these schools aren’t, even if you could get in.
Northeastern is stats-focused, cold, and expensive. Are you liking the idea of a CS co-op program? Apply to U of Cincinnati, which has a terrific CS co-op program. Large urban school, relatively affordable, milder weather, good fit for your stats with at least some merit likely.
If you want to head in a west coast direction, consider the Nevada flagships - far more affordable than the CA publics, both large schools in cities, strong CS programs. UNR is less than 20 miles from the California border.
ASU is a great option. Check out U of Utah too.
How about Texas schools? In Dallas, both UT Dallas (public) and SMU (private) could be worth a look.
UCF in Orlando is a strong CS school too.
