@Michael Barger I agree with the above posts.
The main thing I thought of when reading your post is "be patient". You have time (and money) to cover yourself. Don't put the arbitrary pressure of "I need to figure this out now". I understand you are choosing classes and you want to do things as efficiently as possible, but be patient and know that life things time and trial & error! If you need more time to think or dabble in real estate, you can either sign up for classes and think over the next semester (you have money to do this), or take a semester break.
From a macro perspective, 4 years in college isn't alot of time, you can get great experiences / knowledge, and your degree is applicable to real estate itself. BUT most things are available online to learn, unless there's some new emerging field that only can be learned in college.
Being your age, you have the luxury of time to figure out and hone in on what you want to do. Be a sponge to learn as much as possible and make sure you give things an honest chance to determine if you like it or not. Every path has it's difficulty, it's just choosing what difficulty you can and want to go through. Write it out on paper to keep things clear in your mind.
