Is my GPA okay?

I had a 3.9 GPA at a lesser known college (including A’s in biology, chemistry and anatomy). I also tutored there and volunteered. I transfered to UMass Amherst’s Honors College this semester because it’s a much better program than what I was in. I struggled this semester and got a 3.59 GPA and i’m extremely worried about it. I want to go to PA school and i know I need to do a lot better. Is this GPA something to be extremely worried about? I’m a biology major.
