Where can I get more information on the major recommended to me?

Check the advisement and catalog pages produced by universities that highlight their majors. For instance, check the information pages found at some university sites. All universities have websites that can be accessed to give you information about their departments and majors. Their catalogs will give you additional information. Many campuses run a "Major Fair" for their students. Attend these sessions, even if you are still in high school. The advisors participating will be happy to talk to you and to direct you to information that answers your questions.
