I primarily take night and weekend classes because I work during the day. I was talking with several other students in my major and most of them are in the same boat, which is expected since we go to a commuter school. One of our required classes is only offered 4 times each semester and it's rarely offered at night or on a weekend. It's usually scheduled for weekdays between 8:00am and 5:00pm and the classes are never full. Should we send in a request for different meeting times? If yes, does the request go to the department chair or someone else?

If this is a big no no please let me know. I know that scheduling classes is really difficult so I don't want to come off as demanding and a big whiner.
