Compare to calc BC for example, colleges seem to be less willing to accept credits for AP stats as it’s regarded to be not as challenging. Also a pre-exposure to MVC and linear algebra will be good for computer science, especially when it comes to numerical algorithms and optimization. Taking a one year break from calculus while taking stats might also be not be a good thing if one intends to build upon the calc AP class when getting to college. Unless the student feels overwhelmed with math I would recommend pushing ahead with MVC. Good luck
