You are in the cafeteria. Turn left and walk straightly towards the wooden cabinet. Now turn right and move towards the wooden table. Again turn right and walk straightly in the hallway till you reach near the last wooden table which is on your left side. Slightly turn right and move towards the open door. Walk through the door. Walk straightly in the corridor till you find an half open door in front of you. Walk through the door. Now slightly turn right and move towards the glass wall. That will be the end point.
