The largest Mathematics room in McHenry (1240) holds 48 people but this room is usually completely filled with sections during the academic year, and thus totally unavailable M-F. Our other large room (1257) is similarly impacted. However, weekends are usually completely open even for 1240 or 1257. A more realistic max during weekday prime-time is 20-25 people, but even at this size we cannot guarantee accommodation.
