Is a 3.4 gpa a good grade for my first 6 classes of college?

Hey I have only a few college credits. I've finished 6 classes of my bachelors degree and was doing well but I might get a C in my math class. If I get a C my gpa will go to 3.4 if I get a B it will be 3.6. I want to get into BU law school. Is it still possible to graduate with like a 3.7 or higher if I get a C?
