If you walk down the hall and look at the room numbers eventually you will see that room 318 is not there and it just goes 17, 19, 20, 21, 22.
It seems like a big mystery why they would build a building with a missing classroom but no one will know why. It also turns out there is another missing number on the second floor too. There is a big space between 319 and 320 so there should be a classroom but it is not there. Why is it not there? Did they do that on purpose? No one will have an answer of why it is actually not there.
