You absolutely can do it. Pay attention in class, take good notes, go to your professors when you need help, make sure you do and understand all assignments, make sure to study every day, and reach out for help in general as soon as you find yourself struggling. From your academic history, I’m guessing you already do a good chunk of those things, if not all of them. That in and of itself gives you a leg up over a lot of other incoming freshmen.
My other advice to you is to switch majors if you start to dislike your current major. You can go to medical school with any major, so long as you complete medical school prereqs. So if it turns out biological sciences isn’t all it’s cracked up to be as a major, there’s absolutely no shame or consequence (at least as far as med school goes) in switching to something you’re more interested in. In fact, taking classes you’re genuinely interested in will generally help your GPA more than taking classes solely because you’re required to, with little to no actual interest in them.
Obviously, if you decide to switch you do need to look at logistics like how long it will take to graduate if you switch. But GPA-wise, you don’t generally want to stick around in a major you dislike for any longer than you need to.
