One way a student can demonstrate interest is by going to their admissions page and looking for a link to sign up for college admissions emails. The student can also follow their Instagram account – usually there’s one for the college as a whole and one specifically linked to admissions. They can look the account names up on Instagram directly or on the admissions web page.
