I know students who graduated from both recently. Neither had math beyond BC. One was even homeschooled. Both did very well. One stayed at Caltech for a PhD and the other went from MIT to Stanford for a PhD.
College Confidential gives a false sense of what’s actually happening out in the world. Sure kids can and do take MVC in HS, but it’s the exception. My son would have, but his HS didn’t have the option to jump straight to BC and MVC when he was there. They didn’t even offer MVC. They were forced to take AB then BC. Some school systems are now intentionally throttling back advanced maths. The bottom line is that it’s about maximizing opportunities. If there’s no opportunity to take MVC, it won’t be held against a student.
