Not sure if I'm choosing the right major?

Your choice of a major isn't final; you can change it at any time in your first two years of college, and the new one you pick doesn't need to be related to the old one. You won't have to take biology as a geology major, but you will need physics. If the school you're going to offers architecture (many don't) that's also an option, but again will require physics and calculus. While it's good to find something you're interested in studying, don't avoid it because parts of it are things you're not good at. That's the whole point of college - to become better at something.
