It depends on which colleges your son is applying to. Some colleges don’t consider the “Level of applicant’s interest” while others do. Google “CDS ‘whatever the college’” and go to the section C7. Under the “Level of applicant’s interest,” the college will tell you whether they consider it important, considered or not considered.
If your son is applying to those colleges that consider the demonstrated interest, then there are several ways of showing it:
- Pre-registered campus tour
- "Why Us?" college essay
- Subscribing to college programs
- College Interview
- Talking to college rep during regional visit etc.
