OP, I think it's unlikely (but not impossible) that there will be somebody here who can answer your questions about John Poole MS specifically.
In general, the curriculum is the same at all middle schools in MCPS. There might be fewer different classes offered, since it's a tiny middle school by MCPS standards (351 students, from 2 elementary schools), but I'm just speculating. If you want to know specifics, probably the best thing is to go to the school website and look.
