It took you four years to reach this point. Now you have one month or less to decide where you are going to go. It's given that you probably narrowed your college choices down before you applied. You probably even have a first and second choice. Applications were sent what seems like ages ago.
Colleges get months to choose which students to accept.
Given this may be a hard task because of the sheer number of the applications. But the admission counselors do this as a full time job, they get to sit and think about it all day long for two to four months. Students get a month and they still have to go to school. The costs are also greater for a wrong decision. If the admission counselor admits someone who shouldn't be or rejects someone who should be accepted, they still get paid.
