What does the term 'competitive schools' mean?

There are three categories in total: Dream, Competitive and Safe. 

Safe schools are the ones which have the highest possibility or assurance of you getting shortlisted. Competitive Schools are on the middle ground. They are not too easy to get in, nor too tough. Dream Schools as the name says are the schools which have a low possibility of you getting in.

The schools are divided into these categories based on the profile details that you put while taking the FREE School Explore Quiz here.
