^ I won't be surprised if in the future AACOMAS starts averaging retakes. DO schools are getting more competitive and GPA/MCAT is increasing every year.
In fact, I believe more in AMCAS's policy where they should average retakes. If retakes are allowed, then everyone can be going to DO schools with 4.0 GPA's if they can keep retaking...It makes GPA less relevant and MCAT more relevant.
To me, retaking it isn't fair. It can significantly skew GPA's for those who have only taken it once to those who have taken the class more than once. I mean, shouldn't adcoms take into account someone who received an F in a class and got an A later vs. someone who got a B the first time around? I'm not trying to insult anyone here, but that's my honest opinion.
As a doctor, when you screw up diagnosing a patient, you often don't get a second chance to make things right. Sometimes damage is irreparable.
