Don’t use your limited number of visits all on the most selective schools.
At least two reasons:
- As people note time and time again on this forum, it is very hard to get into those schools even for students with the most amazing credentials.
- You may develop the mistaken belief that only those highly selective schools have beautiful campuses, vibrant student bodies, welcoming faculty, amazing resources, etc.
Save the hair-splitting between Exeter and Andover until after you’re admitted.
