You are in a room facing towards the open door. Walk straightly towards the open door. Turn right and exit the room. Now turn right and walk straightly in the corridor till you find a glass wall in front of you. Now slightly turn left and walk straightly in the corridor till you find an open room in front of you. Turn left and walk straightly in the corridor till you find two corridors on either side of you. Turn left and walk straightly in the corridor till you find a half open door in front of you. Stand near the door. That will be the end point.
