* Starting age: Some students go straight from high school at age 18, while others start later.
* Type of degree: A four-year bachelor's degree will generally take longer than an associate's degree.
* Full-time vs. part-time study: Part-time students take longer to graduate.
* Taking time off: Some students take breaks during their college years.
Therefore, while the *average* age is around 22 for those who go straight through a four-year program, you could graduate anywhere from your early twenties to your thirties or even later.
