Dad is slowly improving, time will tell exactly how far he can progress. Our hope is that he will be able to walk again, but his mind is still sharp, and that's the most important thing! I remember grad school... working, night classes, and then studying. Good luck, you'll be glad you did it when it's over ;) Do try to take care of yourself and don't get so tired you can't do anything well... it's all about balance (I'm still working on that!). Have a great evening, and happy studying!
