Obama's College grades?

With so many gaffes and mistakes, I am wondering what were Obama's grades in College and Law school? What about his SAT score? I remember in 2000 & 2004 election it was a big deal! Remember this headline, "who is smarter Bush or Kerry?"

Well, what about it Mr. O? Let us see how smart you were!

Mr O, refuses to release his birth certificate, will he release his grades?
