@ilovebiology1010 it really just depends what you are looking for. Technically, we are all in the “same class” even though we are at different campuses. We all get ranked together, have the same professors, and have the same curriculum. I am at the Harrogate campus and love it. Knoxville has some great options too, though I’m not there so can’t speak much on it.
Harrogate has an actual campus feel. You are there with other graduate students and undergraduate students. You study on a beautiful and traditional campus and have access to a gym, intramurals, sporting events (basketball, baseball, lacrosse, soccer, etc), and tons of clubs. You also have great volunteer options like the Cumberland Gap Fire Department, the community wellness center, and Lincoln’s Cupboard (an on campus food pantry). Additionally rent is WAY cheap compared to Knoxville. The obvious downside is that it’s a small town without much to do in your free time. You have access to a few restaurants, a few grocery stores, and a large selection of fast food. There’s also some great out doors activities including hikes and rivers. But apart from that there’s not much to do. For me it hasn’t been an issue since you spend most your time studying and then the times you do have off Knoxville is only about an hour and 10 minutes away. And Gatlinburg is only 2 hours away.
I’ll let somebody else talk on the Knoxville campus since I don’t go there. But both campuses are great options in my opinion. Just depends what’s important to you in terms of life outside of school.
