No previous degree, Harvard acceptance?

<p>Curious question for all you Harvard heads. I have a couple of distant buddies, who supposedly go to Harvard now. They are 23 years old, with no previous degrees or anything like that. How could this be?!?!?!? They were both living in California, and I know that they were taking a couple of classes online previously at Harvard, which i assume is part of the "extension" school, but now one of them is living in Cambridge, and they claim that now its not part of the extension, and they've been accepted to the actual University. Is this at all possible, or can there be any explanation? With the level of prestige that Harvard has, i found this a little off putting since i worked so hard to get into my current school, and they were just like one day, "oh, i'm gonna go to Harvard."</p>
