I have a 3.25 UW...what will my gpa be if I get straight A's this semester?

I’m a senior and am looking to be a performance major in college.i go to a rigorous private prep high school. My GPA from freshman-junior year is an UW 3.25. (Weighted 3.56) If I get straight A’s in all my classes what will my UW gpa be after just 1 semester (for applications) ? I really really want to go to the Northwestern Bienen School of Music. I’ve heard from teaches that I can get in on the music side but the GPA is a real issue.
My SAT score will be good enough. If I get great grades this semester do you think this would help my case?

These are my senior year classes:
AP Calculus
AP Literature
AP Psychology
Statistics (regular level)
Religion (elective so I think this doesn’t count for GPA)
Orchestra (elective so I think this doesn’t count for GPA)

Look up “high school GPA calculator” and you should find one that allows you to calculate “what if” scenarios.

Roughly around 1/7 the difference between 3.25 and 4.0, so around 3.36.

Yeah, 3.36…it’s a bit late to make significant GPA changes

BUT often performance majors are looked at for their performance, not as much their GPA so see what your school wants
