What is a "critical course?" What happens if I don't take it?

A course may be critical because it is a prerequisite for future courses. It may be critical in time because it is only offered once a year. It may be critical because it requires a minimum grade, such as "C." The purpose of a roadmap is to guide you through your degree program in a timely manner. Missing a critical course may put you off track and push back your graduation. You may be receiving "warnings" from your college office that you are "off track" for graduation.
