The two remaining spots will go to the team with the highest unqualified programming skills score and the team with the highest unqualified robot skills score in South Carolina. (See this thread) I think these two teams would be 4825A and 9623C.
I’m not sure what will happen because the same happened at the VA state championship. We got 2 spots and right at the tournament, they called up another team and they qualified for Worlds. I’m not sure how they decided which team qualified though.
They decide the teams by choosing the next highest state programming skills rank, then the next highest robot skills rank and so on.
