What is the average class sizes for someone majoring in Kinesiology at TTU?

I am a transfer student looking to transfer to TTU or ASU for the Spring 2017 semester. My major will be Kinesiology in hopes of becoming a PT. However, I come from a small-medium sized community college and I know TTU is a very large campus. What are the average class sizes for someone at the College of Arts and Sciences? Also, with the campus being so large is it harder to make friends or easier?
