<p>Different schools measure “level of applicant’s interest” differently. Could be a combination of having a visit recorded, asking questions to the admissions office, frequently checking your account at the admissions portal on the web site*, writing about your interest in the school in the essays, etc… You may want to ask on the school-specific forum what it counts as “level of applicant’s interest”.
