D17 came out of a rigorous prep school and was top in her class. She took Calc BC and did well. She was told which Math class to take by her adviser but went against his wishes and took a class that was mostly review for her because she felt she didn’t have a handle on the material, despite having an A in the class and a 5 on the AP. She ended up taking the next class in the sequence during the spring. This required her to make room for an extra Math class but ultimately set her up for success. Sometimes the kids need to think about understanding the material rather than blowing through requirements they may see as a nuisance or uninteresting. They also need to understand that when they are at a highly selective school they are surrounded by other really smart kids, some of whom will be smarter and be able to handle the fast pace of a college class - and blow the curve. There is nothing wrong with taking a class as a review or switching into a lower level class if you need more time/instruction.
