Great news then! At least it's a straight answer and you know where to go from here. :-)
Yes, it's good news. He doesn't have to go to any classes...these are research hours and done on his own time. She could have told him it was too late, to take the two hours this summer, which wouldn't have been the end of the world, he could walk the ceremony in May and just signed up and paid for the hours in the summer, again without having to actually go to any classes...would have been merely a formality. But he wouldn't have graduated till mid-summer, no ceremony. Just that much longer to wait to have a diploma to wave at potential employers!
