Do I still have a chance at T30s if my ACT is 35 but my uw gpa is 3.7? (4 pt scale)

In many cases “top 30” universities can be competitive and stressful. Students can vary quite a bit in terms of whether or not they find that this can lead to burnout. Even some individual students can like this at one time and not like this at another point (whether a few days apart or a few years apart).

What do you want in a university?

As others have pointed out there are thousands of colleges and universities in the US. You should look for schools that are a good fit for you. Unfortunately finding a good fit can be more difficult than just looking at ratings.
