I can just say that mine was "validated" almost the day I sent it in, then a month later I got an a second email saying it was validated. Like someone just said, the administration in any large french institution is just out of whack sometimes. I'm living in Paris now and I'm around Sciences Po students daily, french and american, and they all seem to say the same thing, admin is going to make you want to punch someone. So, if you think you have bad news coming, it is more likely they are just taking their time.
