Your college office can help you navigate the requirements for your current major and to learn about the requirements and processes should you wish to change your major. Newly admitted freshmen are to remain enrolled in the major to which you were admitted for at least two semesters.
If you are considering a change in your program of study, Office of the Provost Guide to the ICT Process website is an excellent resource.
