Typically, it does not matter how you number your university or program choices in your application.
Whether you list a university or a specific program as first, second, third, etc., in the application is not usually a factor in the universities’ admission decisions.
A university must make its policy clear in its own information where there are exceptions. See the university information pages in this application guide for more information or contact the universities directly.
Your numbered list of choices does provide valuable information to university admission offices. This is particularly true for limited enrollment programs. Admission officials use this data to project the number of applicants who are likely to accept offers of admission, so the university can plan its resources accordingly.
