What are my chances at getting into Brown University?

Hello. I would to apply to Brown University with an acting major and when I was reading the requirements to apply as a transfer, I got nervous.

The reason why I got nervous is that they ask for an official high school transcript. My transcript is not the best. I have a B average GPA from high school, but I currently have a 3.78 GPA in college.

Do I have a good chance at getting into Brown?

Another question that I have is what is a good ACT score to get into Brown University as well?

I’m also hoping to apply to Brown as a transfer from a community college. I currently have a 3.75, it’s my dream to go to Brown but I’m also going to apply to Penn, Columbia, Georgetown, and University of Texas. I had a B average from high school as well. my test scores are trash, what even would be my chances?
