regarding AP

hi guys.I’m from india and i’m new to this system.I’m an aspirant of MIT,PRINCETON,HARVARD,STANFORD,UPENN

Can someone tell me that whether AP exam is necessary or maybe beneficial for above mentioned schools?

No, it is neither necessary nor beneficial. Many schools do not offer AP courses, and students from those schools get accepted to elite colleges every year.

Beneficial, maybe, since you can use high AP exam scores to count for college credit. Necessary? Definitely not.
