<p>Sorry, but I don’t think that’s true. Taking a bunch AP courses is not enough to get accepted to an Ivy, and that person must have been rejected for other reasons. There are plenty of kids who take AP classes in fields that they’re not planning to major in. It’s just more interesting than wasting your time in regular classes with zero courseload. I’m pretty sure that the admission officers see it the same way, and will never reject a kid because he/she took too many rigorous classes in different and unrelated fields.</p>
