What you did is fine. I had updated it to match the signage I've seen outside when walking by, and also the school names listed in the building found on the DOE website's own map. I had never heard of the "crossroads" school that it was previously labeled.

I don't know if makes any sense to add an additional edu POI marker for Mot Hall II, which as I understand it occupies the 4th floor. But again, I'm satisfied with your changes.
