It is CRITICAL that you spend time doing Maple outside your lab class. To facilitate this, lab staff are on hand to assist you during open hours. They'll selectively open Blocker 131, 130, 127, and 125 (in that order), based on demand. Under no circumstances are you to interrupt a TA's or instructor's lab class, day or night. Either wait until open hours or go to a TAMU computing center (see the next subsection). Schedules are posted both in the CalcLabs and electronically on the Web. They specify exactly what goes on in each room each hour of the day. Here are the current open hours.
DAYS HOURS Monday-Thursday 7:00 pm - 12:00 mid Friday (BLOC 127) 9:00 am - 5:00 pm Saturday 12:00 noon - 6:00 pm Sunday 12:00 noon - 12:00 mid
