<p>This can become a problem if not for admissions, then for students who are taking a class that is no longer taught as a true introductory college class, but as a review and extension for students who are presumed to have mastered at least some of the material in a high school classes. </p>
<p>Wrt admissions, however - </p>
<p>At our high school, BC calc covers much of what is covered in calc 3 at most colleges, and the teacher goes well beyond what is needed to get a 5 on the AP exam, and offers bonus problems that give truly excellent students a chance to stand out from the crowd that does enough to get A’s. I cannot imagine that a student who waits until senior year to take AB calc but then distinguishes themselves in this class would be at an admissions disadvantage compared to a student who works hard in junior year calc and gets an A and a 5, but does not truly stand out.</p>
