I am someone who spent months perfecting their personal statement. However, I always imagined admission officials reading it in 2-3 mins and checking a box if it was good. I know most top 50 schools stress that they take a holistic approach and also say that your essays might be the most important part of you application. But in reality, with the amount of applications each college gets, I really doubt adcoms thouroughly read each personal statement. You also have to consider that most colleges have supplement essays to look at as well.
All in all, I'm trying to see what College confidential users have got to say. How important are your college essays?
