Checking in again.
I don't know how far you've gotten with the college stuff, but here's my advice, for what it's worth. I've dealt with a few universities in my day and they can be tedious bureaucracies, but Davy should have every right to be excused for this semester. Smaller schools can be easier to deal with. I don't know about Davy's college's policy or terminology, but he would want something like a retroactive withdraw. That means that his withdrawing from classes this far into the semester will not reflect on his GPA or whatever metric the college uses to track a students overall performance.
In other words, you should ask the college if they could excuse him from classes without adversely affecting his academic record. Otherwise, the college might treat him later as though he simply bailed out a semester. Also, if your costs were out-of-pocket, then you might want to ask them about a prorated tuition refund. If the semester was financed through a scholarship or loan, then you will need to contact the organization behind that. For a student loan, you will need to ask them to not start asking for repayment yet.
As for dealing with the college, bear in mind that not every clerk knows all the rules, only enough to get them through the day... and many of them are just college kids. I would suggest finding someone, knowledgeable and sympathetic in the registrar, or perhaps one of Davy's professors, to help you out, if things get sticky or confusing. Some of the larger universities have some kind of student advocacy on campus, which should be a good resource. Also, this is another situation where you need to effect as much sympathy as you can, don't be confrontational, but be persistent with your case. I'd recommend starting with the phone. It's not as effective as face-to-face, but a lot easier in the beginning. Otherwise, you'll could end up running door to door all over campus.
I continue to pray for Davy's improvement and for the well being of his wife and family. God's speed.
