do colleges really throw out apps that don't meet the gpa and sat/act requirements first?

Many former admissions officers state that they use gpa and scores as base case for the student to be successful.

If below this threshold, they will continue to read your application looking for the remarkable or particularly unique.

They won’t throw out your application.

It’s in absence of a compelling situation or institutional need, you will be simply moved into the category that won’t warrant further review.

This is hard to define because each reader has a different set of values and interests. It’s not easy to predict.

Also, if you do pass the first read with lower grades and scores, it doesn’t mean admission. It will be difficult for your AO to sell you to the senior team or committee.

It will be rare.
