* Credit transfer: Students may transfer credits from previous coursework, potentially shortening the time.
* Course load: Taking more credits per semester can accelerate completion.
* Summer courses: Attending summer sessions can also reduce the overall time.
* Major requirements: Some majors require more coursework than others.
* Part-time study: Studying part-time will naturally extend the duration.
So while four years is the standard, it's possible to finish sooner or later depending on individual circumstances.
