MCAT scores come as a distribution. Even if I average a score of X on my practice tests, on the actual thing I may do better or worse without any change in my true ability. The more tries you need to get the same score, the less credible it is because since you're taking the highest score, more retakes means I have more chances to have things go my way.
That's a good point. In fact, I don't know how much variation we're talking about here. Does anyone know (is it X +/- 1 or it is X +/- 4, etc.)? The answer would affect how I would 'bin' the scores. However I would still take the highest score - I would just consider it as equivalent to other scores within the same range (ex: 30-34? 35-39? 40-42? 43+?). What do you think? To me, this would address the problem of credibility but still give the applicant the benefit of the doubt.
Anyway, the "strength" of having the confidence and discipline to fix their weaknesses and do better is unlikely to be seen as superior to the confidence and discipline to prepare better and just do well on the first try.
I would disagree. Everyone encounters difficulty. People who suck it up, reflect, have the self-awareness to fix their weaknesses, try again, and succeed on the MCAT are likely to apply the same attitude when they meet later challenges: it might be a difficult procedure, new and weighty responsibilities, or unexpected life challenges. This is indeed a strength, not a "strength". Of course, I would never take a person with a 35-->42 over a person with a 42, but I would never take a person with a 42 over a person with a 35-->42 either. I would decide based on other factors.
Now, the applicant who does well on his first try. A MCAT score of 45 means you have strong academic preparation, you're brilliant, you've honed good study habits. But I disagree that this implies confidence or discipline in the face of failure, and by extension, that this implies the 45-er has the same strengths the 38-->45-er has. The strengths are simply different.
HOWEVER, it's assuming a lot that we would know why the 38-->45-er improved. That was my point. To me, if you're looking at an applicant with a 40+, whether the result of natural brilliance or after a retake, you have yourself a person who's got a sound grasp of scientific/logical concepts at the time of application. To go beyond that to assume initial laziness or resilience is silly. I'd move on to other parts of the application.
LizzyM, I hope this also answered your question. Just to add that sure, the re-taker will likely have been a weaker MCAT-taker on his first try, but he's got what it takes by his second. What I think the OP is asking is whether someone would hold it against them for knowing their Orgo in a test date in July but not the one in March. If you would, I'm curious as to what you'd be assuming about him/her that you wouldn't with the person who may or may not have known their Orgo in March but didn't test, but did in July. Mis-gauged how prepared they were in March? How big a weakness is this to you?
