Walk all the way down the hallway to the second exit sign.
Start moving forward down the corridor. You will pass offices on your left and right. Keep going until the hallway down the hallway until you get to an exit sign on your right and what looks like some lockers in front of you. There will also be a brown door with an exit sign above it in front of you.
Walk down the corridor and keep going past the class offices. Stop outside of the area with the lockers. Stand next to the exit sign.
