People tend to check in during these times:
Look at the fire escape maps to find your classroom here. They're posted at every entrance and on the walls in the hallways.
If you didn't get lost, you're probably not doing it right.
If you're class is in the 100 blocks don't walk through the entrances across from WRB. Side door facing parking lot. PS you will get lost here
Don't let the classroom numbers fool you. There's a map on each floor so look carefully so as not to get lost! And there is no third floor even though the elevator says there is!
