Great question, Cierra!
I wasn't always very engaged when I was in college. Many times, I took a class only to find out a TA was teaching the class that wasn't very good or that the professor just gave a boring lecture out of the textbook. And, unfortunately, this will happen A LOT.
The bright side is that there are tools to help like: http://www.ratemyprofessors.com/ You can pick your school and your professor. It's been around for about a decade so there's a good change your college will be on there.
Although it doesn't sound like your professors may be there...
The best thing you can do is network with students who are 1 - 2 grades above you. You can do this by joining organizations or attending events your school has. When you have a solid network, you can ask those people who just took the class about the professor and hear first hand about their experience. It'll also help you be more engaged at school because you'll be able to learn from their mistakes.
