My DSs (plural..but that looks funny) aren't as old as yours, so I surely don't speak from experience.

That being said, I say you go to your invite day and see how your DS likes it. Personally, I would request an invite "week"..so the like isn't too colored by the novelty of the school.

I would also want to know what happens when your DS passes their final grade in any one skill - looking like math..and soon. Will they allow him to take college courses?

For me, GT means Georgia Tech.
