Back again with another request for hints because I’m still struggling
Specifically with opening the Office’s Door.
I’m pretty sure you need to jam it open with something, but neither the hammer, mop, torch, outfits, card, help. I’ve tried also picking the lock with all items I found (I left my pen back in the classroom).
What I’ve done so far:
Opened my locker, found the coin and exchanged it for batteries (also the torched is fixed), flushed the toilet and told the janitor.
