If you finish the eam 5 minutes before the ending time, you may leave the room after turning in your scantron sheet and the eam booklet. If you don t finish before 5 minutes before the ending time, you should REMAIN SEATED until your TA comes and collects your scantron sheet and eam booklet. Do not talk to other students until after you have left the eam room.
Eam Policies. Students must sit in preassigned seating areas.. Students may not open the eam until instructed to do so.. No student may leave in the first 0 minutes or in the last 5 minutes of the eam. 4.
