Attend any career days or school fairs that are available at your high school, particularly if you are a high school senior. Colleges and universities will be represented at these events, and you can visit their individual booths or tables to sign up for their mailing lists and receive general information about the schools.
Visit the websites of any colleges that you are interested in attending. On each website, find a contact link that allows you to sign up for the school’s mailing list or to request specific information. If you can't find the link right away, skim the admissions or recruitment section of the website.
Visit some of the universities in person that you are interested in attending. While you are there, meet with a representative in the admissions department and ask to be added to the school’s mailing list.
Call the admissions office of the university of your choice and ask to be added to its mailing list.
