Attend college fairs in your towns at high schools and other venues. Colleges and universities will be represented at these events, offering information about the school. Sign up for mailing lists of schools you find interesting.
Visit the college or university in which you are interested. Take a tour of the school and ask the admissions office to put you on the school's mailing list to receive newsletters, event reminders and other information.
Go to the websites of the colleges and universities you are interested in. There is usually a link to a sign-up form from the home page. Fill out the form and you will be placed on their mailing list.
Call the office of admissions of the college or university you are interested in. Ask how you can be placed on the mailing list for the school. Someone will usually either take your information directly or direct your call to the person who can help you.
