According to the University of La Verne, the percentage of students who change their majors is between 50 percent and 70 percent, although the exact percentage varies by school. The university also notes that it's common for students to make three major changes. Many students enter college undecided about what they want to study.
Before changing majors, students should check with the school to find out if the classes they've taken apply towards the requirements of the new major. While general education classes, such as those in math, language arts, social studies and science, often do transfer, other classes in the previous major may not. In addition, it may take longer to graduate depending on whether additional courses need to be taken.
