And to elaborate on nspeds' comment, to trace the rampant grade INFLATION at elite schools, just go to gradedeflation.com. I think Harvard's avg. GPA is a 3.3ish, while UT's average GPA is a 2.6ish. State school professors really are not hesitant about assigning C's, D's, or even F's to students that don't put enough hard work in. The students with that same mindset to blow through college and not to put too much work into their schoolwork end up with B's at Harvard, when they should've gotten C's or D's.

<p>The reason for this, in my opinion, is the cultural or social factors in each school, including the attitudes that students bring with them. Students at Harvard have higher expectations, generally have a better idea of their limits, and are less risk-averse academically. Also, what their peers are doing has some effect. They have better advising, smaller classes, and have more students (%) operating under parental pressure. </p>
<p>Professors at state schools have been accustomed to give out those low grades because of the more extreme behavior of the students. The type of student that may sleep most of the day, party most nights, smoke marijuana, not attend class, take the midterm absolutely cold after 9 weeks, and simply have less of an idea or concern for their future is simply much more common at state schools. I don't know, elite college students may "party hard" but it is with a markedly different mindset. Another thing I have noticed is that people in state schools downgrade their major more often than at elite schools. </p>
<p>I think also that students have a tendency to make the grades they have been making and not want to go much lower. Since they started out with a significant difference in grades to start (look at the percentage of valedictorians or average gpa at elite schools compared to state schools), this fits what happens. Elite school students might drop from their typical A student entering status to B, but state of course is B-ish to lower, and then, in my view, it becomes a slippery slope in a good deal of cases. </p>
<p>That "same mindset to blow through college" is almost never the same. Dropout rates are another effect in favor of elite colleges. Students who want to "blow through" Columbia are very likely to do just that; more than a few state-school students never fulfill that modest expectation. </p>
<p>I am sure there are plenty other reasons and evidence but the main point is that when you are dealing with two different student bodies AND grading structures, comparing them by those shallow factors including gradeinflation.com is basically useless.</p>
