I scored well over any entrance requirements for any Ivy League school, including Yale, Harvard, MIT, Reed, etc. However I learned early that Ivy League schools generally offer much poorer education than other institutions, like Fine Arts schools. This is because these Ivy Leagues exist due to the backing of the very establishment you are rebelling against.
I can talk circles around Yalites becasue they are brainwashed with only the accepted material and views and are never challenged to step beyond what is offered...indeed they are punished for original thought (unless it makes a buck).
As for intelligence it depends how you mean. If you mean overall intellect then it's very probable...many people have a broader range of knowledge than I. If you mean raw standardized IQ scores, well it's possible, but would be very rare as I score rather high on those. Either way intelligence is not what we're talking about here. What we're discussing is maturity and personal responsibility - and any back woods redneck moron can possess those qualities (and they often do).
