There was another thread about this, but the three best predictors of Step 1 score were MCAT Bio, MCAT Phys/Chem, and the average Verbal of your undergraduate institution. The correlations were decently strong (0.44-0.55). It's weird, but the former two at least make sense since Step is also a sit-down science exam. As an aside, I hope the latter doesn't encourage more inbreeding of top institutions. Undergraduate Institutional MCAT Scores as Predictors of... : Academic Medicine I don't have the other papers available, but there was data that MCAT verbal scores predicted success of honoring rotations. I don't have direct numbers on this either, but I keep hearing 25-26 (499-500) as the minimum score you should aim for on the MCAT. Adcoms here have said that scoring below that amount puts you at risk of failing boards---though obviously your mcat can't predict your Step 10 times out of 10. I think having 500 as a rough cutoff actually shows how the MCAT is not the end-all-be-all, and that you should not always pick students with the highest scores when designing a class. Someone's potential and capabilities cannot be summarized in a LizzyM score. I don't think other posters were contesting this. Still, while the MCAT isn't everything, it is pretty darn important.
