Welp, it's the first day of the rest of Bella's life. Hopefully the vast majority of it won't be in the Scholomance, and putting her head down to work on that starts with... room 76, apparently. She finds it, after kind of a lot of looking, backpack on her shoulders and magic shoes skating her down the stairs. It's next to rooms 7 and 700. Whoever did the room numbering here had some kind of problem.
The door to the room is already standing open, so that's kind of nervewracking; she listens, first, trying to hear in the gaps between foot traffic and chattering whether there's anything in there, but it turns out it's just a couple of students who got there first. The room looks like it might have been intended as an auxiliary lab; it lacks the specialized equipment, possibly cannibalized years ago, but it has tall stools and stained counters and the remnants of an eyewash station. Bella checks a counter, checks a stool, sits down and nods at her fellow students.
