I've no idea how stuff works at Yale, but I just came across this GS poster who claims to be familiar with the workings of Yale and its rink; see the post
here.
Basically s/he lists the reasons why the Yale rink is not a very suitable base for serious training, so Nathan would have to do some commuting. Also when it comes to balancing school and skating, Yale apparently doesn't allow part-time attendance, etc. etc.
But I expect Nathan to have a very good idea and a detailed plan re: how and to which extent he's going combine his studies with his skating. It's just that we're not privy to his plans and all we can do is wait and speculate.
