The science mean (in general) at Duke falls at a C+, with some classes at a B-. It is true that we have +/- grading, but there is no additional GPA boost for having a 4.0. There is NO grade inflation whatsoever in the sciences or in pre-med classes as a whole. A study done comparing state schools and private schools is interesting, but when I noticed that the private school used was Harvard, I became disheartened. Harvard is well-known for rampant grade inflation, it's been in the public eye recently on just how bad it is. Most of the students who go there, however, are very, very intelligent and it's probably Harvard's way of rewarding those students. A reasoned, logical analysis comparing grades would better be done using a variety of state and private schools, but eliminate the extremes such as Harvard.
Additionally, I would imagine most schools implement a curve in some respect. But, at a state school for example, the students competing for the top grades are not all from the top's of their high school classes and only a minority of the students in such classes are truly competing for the best grades. But, you cannot give C's or fail the bottom 90%, and so the curves are set differently. I have had the experience of taking classes at both a state school and a private school and I breezed through the material at the state school. I worked hard, but not as hard as I did at the private school to get the grade I did.
I am in no way discrediting someone who graduates from a state school with a 3.8 GPA or better because that requires a lot of time, patience, and hard work. But, what I am saying is that someone who chose to be in a more competitive environment to begin with shouldn't be penalized for having gone that route. Afterall, medical school is competitive. Trying to get in is one thing, but being in it is another. Someone who has spent four years in a more competitive environment academically--I would think--has that much of an advantage while being in medical school. I don't want to sound high and mighty about being a private school grad, but I hope that makes sense.
Also, I don't know if anyone else agrees, but I am wondering if this problem I face might have been more exaggerated last year due to the problems with AMCAS 2002. Because medical schools were behind in selecting students, perhaps undergraduate institution wasn't taken into consideration as much in order to fill the class.
