I would get him in to see the disability and councilling team. They will talk with him and write a letter on his behalf. It shows he is serious about fixing the issue. In my degree, you need to keep over a 5 and for a while i dipped to 4.8 i was put on probation but proved i dipped due to circumstances beyond my control. (Ex husband didn't pic up kids and i had to get to a field prac that had mandatory attendance or subject fail).
