Sewing machine usage

I’m a new continuing education student and am taking a sewing course this semester. I want to use some of the sewing machines in the classrooms to complete homework assignments, but I noticed on the FIT website there’s some stuff about needing at least two students to work in a classroom and having to check in and out. My availability hours vary and can be weird at times, so I was wondering how strict the school is on these rules.

Is it fine most of the time if I just walk into the building (Feldman center) and find a vacant room and start working? Are there frequent sweeps of the rooms in which case I’ll get kicked out for working alone?
