And I wonder how many second time applicants really get competitive. Sure, a lot will retake MCATs, fix weaknesses, and get more experiences, but at the same time, AMCAS data says that a ton of MCAT retakes are less than the first score, and only the truly motivated will have turned a rejected app into a competitive one.
If a lot of reapplicants are extremely improved, then this is like a perfect storm! They will 1) have improved apps, and 2) have the reapplicant thing going for them, since I've heard multiple times that it shows persistence that is veiwed positively among adcoms. So a larger pool of applicants, and a greater proportion of that pool that is more competitive than usual!
