If you randomly choose the specialized course curriculum of an American university, you will find that the math class of freshmen and sophomores takes this road:
Pre-calculus->; Univariate calculus (equivalent to AB+BC of your AP)-> multivariate calculus; Simple linear algebra->; Ordinary differential equation; Abstract algebra->; -> partial differential equation; Various topics of advanced mathematics
Computer science can lay a foundation for the use of two commonly used mathematical languages, R or MatLab, and can also introduce a little bit of very limited linear algebra (matrix, matrix operation and transformation).
Statistics is Physics 2 (Thermodynamics), which challenges mathematical modeling and applied mathematics.
In addition, regarding calculus, I recommend james stewart's Calculus 7th or 6th edition, which is a classic textbook in universities. It covers almost all aspects from one variable to ordinary differential equations.
Good luck.
