I'm a college counselor. There's too many details to describe what I actually do but here's a few things I'm in charge of in a nutshell: talk to a lot of students, audit their schedules to make sure they're not taking unnecessary courses, discuss policy updates to make sure they stay compliant with their federal aid every year, discuss potential schedule changes for core courses newly available. It's pretty much a constant compliance and auditing check with 600 students over and over again. Super fun.
Don't work with nursing students, they're b****es.
