I went to a math oriented boarding school. When one started school, a test was administered to determine one’s initial math course. Students began their studies in a range of classes from Geometry all the way to MVC/Analysis. Having seen the standardized test scores and GPAs of many thousands of students at this school, and knowing many of these individuals personally, there is, at best, only a weak relationship between their terminal math course and their intelligence. We had kids who started in geometry and received perfect GPAs and SATs and were brilliant. We also had kids who started in Calc 2 or MVC and barely graduated.
