<p>I think that this depends on the student. What is their major? Did they change majors? Will they have to retake courses due to poor grades? Are they taking a full course load or light course load? Are they taking a semester abroad?</p>
<p>Our D is a freshman. She has carefully planned out her entire 4 years. She anticipates being able to easily graduate in 4 years if all goes as planned. However, she has mentioned two friends who already know it is going to take more than 4 years. Another friend will be graduating one semester early.</p>
