is the academic index real?

<p>I’ve been searching this whole day for AI and many articles say that AI is used by most schools. And it makes sense right? Instead of looking at myriad of numbers and grades of thousands of students, wouldn’t it be easier for officers to judge an applicant’s academics by one number? </p>

<p>I’ll tell you why I’m interested. I got a 600 in lit. Penn ED decisions come out tomorrow. Now I was really depressed about this lit score till I calculated my AI. It came out to be 7 out of 9, which is not that bad imo. So basically my question is, will one bad lit score put my app in jeopardy?</p>
