Responding to this late, maybe too late for the OP to see this.
I normally don’t recommend heavy acceleration for math, even for exceptionally talented math students. But given you are going to finish Calculus as a sophomore, you need to have some type of math the last two years.
I think that @MYOS1634 offers very good advice, particularly if you want to challenge yourself. But in terms of admissions chances, high school stats will be fine as well.
