There is no time limit on getting a degree. MANY people do not complete a degree in four years time. Think about kids who pay their own way, mature students, people who take gap years to work or travel, unexpected family health crises, and so on. No, it doesn’t look bad to take longer to get a degree. Bad grades in too many classes does look bad. If at all possible, withdraw from a course immediately. Next time, don’t bite off more than you can chew.
