Low-Rated Professor vs. Online Class?

I need advice on what I should do. I have Professor Wendy Dixon for BIO110 and I’ve seen bad reviews of her. I already am not good at bio ever since high school so I’m kinda intimidated by these negative reviews. There is an online class availiable with Rothman, but I’m not sure how online classes work. Do they ever have to meet? I heard Rothman’s grades cumulatively on 4 tests total, but is somewhat easier. Should I suck it up and take Dixon’s class or take a risk with Rothman’s??
