You are in the gym room facing towards an open room. Turn right and move towards the open door. Walk through the door and exit the gym room. Now walk straightly in the passage till you find a closed glass door in front of you. Slightly turn right and walk through the open arch. There is a pillar in front of you. Walk straightly towards the pillar. There is a closed door on your right side and glass windows on your left side. That will be the end point.
