While some people may be able to get away with small exaggerations due to the sheer number of applications a college or graduate school receives, the admissions officers have been doing their job for years.
As such, they have experience on their side, and they have a trained eye to point out inconsistencies.
A spotted inconsistency can lead to a verification call. And when school authorities note an inconsistency in your application, they will be sure to go back and double-check to verify your claims.
If the school finds out that you lied in your application, your chances of being admitted are very slim, if not nonexistent.
So what happens if you’ve already been accepted? The school authorities may revoke your admission at the time of discovery. And it may not matter that you’re already halfway into your course.
