It appears that you hit the nail on the head when you said you were looking at online education material?  I posted two replies below the last one being about some matching company for universities?  Good luck.  At least it is not some bill collector or other bad news.  
Still the guy just hanging up on me after I identified myself is creepy too!

Never ever answer the phone with yes. You don't have any idea what that Yes could cause in the way of monetary problems. Do consider maybe getting a call blocking device or phone.. You can google them and many are around $60.00 or so.

It's a scam....don't answer, don't speak. Hang up and report them.

Seems to be a scam number that somehow gets your number when you start researching education or jobs. I've gotten 5 calls from this number in the past 2 days. Very annoying!

Were you able to understand this person when he talked... because this person did the same thing to me and once i identified my self he hunged up he said that he was going to call back later....Did he say that to you????
