Fun fact, if you see in the course catalog that’s listed as Remote/Online, check the scheduled times; if there are some, they’re either mandatory meeting times or in-person testing days; if there’s none, then it’s a fully asynchronous class you can THEORETICALLY complete in parallel to your job, whenever you like.

You could dip your toe in the water very slowly the first term and set calendar reminders for the drop & withdraw deadlines. At worst you don’t like it, at middling you realize you can’t multitask school and work, at best you pass the course. One step closer: wax on, wax off.
