Putting my epidemiologist hat on (yes I did go to grad school for that)...
There are lies, damn lies, and then statistics. I am familiar with some of the researches Ditch provided. Most researches nowadays have flaws, even those published in JAMA, NEJM...etc. When we were in grad school, we took apart articles from JAMA/NEJM and analyzed them with strictly epidemiological methodologies. We requested raw data from the PI, and re-did their statistical analysis. We were very surprised that many times, we came up with very different conclusions by making different (and equally valid) epidemiological assumptions. There are very few articles in journals that pass the smell test when analysed purely from an epidemiological views. Correlation does not equal causation. Too many variables and confounders are in the mix. An example -- I bet you I can do a research and convince you that ownership of a Zippo lighter "causes" lung cancer. BTW, my undergrad college pre-med adviser and my undergrad major adviser both told me I would never become a dcotor, despite the fact that my GPA/MCAT fell in the range of national average of accepted US medical students. I think I just taught one of their kids in medical school... 8) P

a while back, my stats prof (who i have deep respect for & faith in his ability!) told me stats can be manipulated or changed very easily. this i learned myself, due to the class.
also, he told me HIS (personal & private firm) research on standardized tests & their correlations with success rates resulted in most standardized tests as garbage (in their ability to predict)! the validity (tests what it sets out to) may be there (in some cases, i.e. MCAT) but that is about it. The test results cannot be generalized to everyone, and are not 'consistent' (what is that bloody word?). THE LSAT however is a good predictor! this is the only standardized test that actually works! |

i think an interesting study would be the correlation between people posting disagreement with the validity of NYU's clearly reasonable advice and an MCAT score < 30... of course, there would be obvious selection bias in this study, because the likelihood of the average VMD user having an MCAT score < 30 is extremely high.
at any rate, the assertion that an individual's performance on one biological science-based standardized examination would correlate with his/her performance on another biological science-based standardized examination doesn't seem very far fetched to me... and the numbers seem to support it. |

Mcat
Ditch DOctor,
You maybe right about the correlation beween the MCAT and the boards but you are leaving out one important scientific factor. That is the MCAT "selects the better test takers. It does not mean really how much you know. I read about the history of when the MCAT first came out. The reason the test started anyway in the 1930's was because there were too many complaints about people not having the basic science skills before entering medical school. From the 1930's until about 1992 the MCAT swithced styles and went from competency test too a filtering test because they needed a way to cut down on the number of applicant like Europe still does. As a physician now I can tell you that I did well on the MCATS "33". The most important thing to remember is that you will forget all the basic sciences when you begin your practice of medicine. PLease dont buy into the MCAT baloney. It is a way to weed out. Yes you can give documented proff about the step 1 so what but remember that you only select out the better test takers. In my personal experience I can give a rats *** about if you know know the configuration of the ribosome. I am sure you will figure out a smart *** comment to say. I am going by my 27 years as a general sergeon and a graduate of Dartmouth. As long as a foreign medical graduate can pass step 1,2, 3 who gives a rats ***. Go study and stop the sarcasm!! |

The MCAT is a very good indicator of a student's success in medical school. |

Being able to get a good MCAT score may have relation to;
#solid study habits #good exam prep (targeted) # good test taker seems all of the above wou;d generally help anyone in their studies. Countless grads from countries that simply do not have an mcat pass usmle. i know a 3rd year resident in thailand (years removed from basic science) and busy working, scored 98% on usmle1 I say the result with my own eyes. And last but perhaps foremost, lets not forget how much $$$$$$ MCAT generates. How I wish mcat could help me not forget some song lyrics.....

The MCAT actually levels the playing field in terms of admissions, some people might have a 3.8 GPA others might have a 3.2, the person with the higher GPA may have taken a lighter major or went to a less competitive school. I knew people who transfered to my undergraduate school who had very high GPAs before they came and wound up graduating with grades in the low 3.0 range.
