you got a 5 on the AP Calc BC test and are planning on taking Intro to Calc in college? are you kidding me? do you have any idea how badly you're going to rape that class? haahahaha
you don't have to specifically take Calc1 in college to fulfill your premed requirement because you can take an even higher level calc class and use that as your credit. it'll look better too, IMO.
I got a 4 on my AP Calc BC test, which gave me credit for college Calc 1 and Calc 2 automatically, and took college Calc 3 during my freshman year. College Calc is so much easier than HS calc, IMO, because they only have 1 semester to cover all the material so they have to leave out some of the more complicated stuff. my calc BC class in HS was way harder than my calc 3 class in college. I got high As on every calc3 test in college without doing much of the homework haha. 👍
