So far, despite obviously seeing the benefits of it and having taken 9 AP classes, only my Chemistry teacher has voiced this as an effective option. To add to that, said Chemistry teacher (from Auburn, one of the consistently harder schools to get an A by many sources) added that if you don’t skip a class that you are very good at, you’ll have the added benefit of probably getting an A in it on retake, which would count well towards your college GPA.
Good suggestion.
