What if one parent is a cardiologist that divorced the mom and the mom had to raise the kids herself? You won't get financial aid on that salary. There is also a difference between say a top 20 and Harvard.
On the FAFSA as well as the school-specific financial aid forms, there is a place to note that your parents are divorced. You can also list special circumstances like "single-mother raising child by herself." As a last resort, after financial aid packages have been awarded, you can request meetings with financial aid officers to discuss the specifics of your case. My friend did this and got upwards of 10 grand added on because his family is supporting not one but three children through college - otherwise he would not be where he is today. It depends on the college, but since I was only talking about the Ivies, I know for a fact that all of them have generous financial aid packages. For me to attend any of them, I would have had to pay less than attending my state school which I also applied to. The margin was huge - no more than $10,000 a year for the Ivies+MIT versus $30,000 for state school (tuition, room, board, books, etc. included in both). Like I said, circumstances differ and single parents raising their kid alone is definitely taken into account.
Finally if you're sooooooo smart compared to those state kids you'll crush them on the mcat. If you claim the mcat isn't reflective of your performance in college then why bother correlating GPA to mcat for ad coms?
I have never correlated GPA to MCAT for adcoms. I've only said that GPA should be weighed differently between schools. I also have never claimed that MCAT isn't reflective of college performance. I only claim that for
some non-trivial subset of the population it is not reflective of performance. What I have said is that many other factors go into the MCAT besides wealth. For example, a student at a top school likely does not have as much time to study for the MCAT as a student at a less rigorous school. Easier competition, a less demanding courseload, etc. all make for more study time for the latter student. At my university, independent research projects take up a huge part of the junior and senior years. Summer research during the junior summer is essentially to doing well on the mandatory thesis. Study time is therefore severely cut into. Not only that, but during the school year, people are studying all day, every day. It's like like you can finish your homework and then study for four hours a day for the MCAT. I've been to friends' state university campuses. You'd think that their side-job was going to college and their main job was playing video games. The discrepancy is obvious.
Finally say you truly are amazing in class, but bomb the mcat. Who is to say you won't bomb the step 1? If anything for practical reasons an ad com would be more interested in the state student that does well under pressure and can ace standardized test so he doesn't have to worry about dealing with the 1 guy that failed the step making the school look bad.
Like I said before, I'm not saying that the student breaks under pressure. I'm saying that many factors go into doing well on the MCAT. In a minority of cases, perhaps the student was sick the day of the exam. That's a small group but medically, studying day and night weakens your immune system. A more pressing issue is the issue mentioned above - the differential study time of students at different universities. Less study time = worse relative performance. The one contradiction to this argument I must acknowledge is that the average MCAT scores of students at top universities are extremely high. That must mean that they can either A) do well without much studying or B) take time away from class work to study for the MCAT. The latter case would lead to sub-optimal performance on schoolwork.
Even if you could account for rigor on a school level accurately, what about on the professor level? At some point you just have to embrace that there is no objective/perfect way to compare applicants.
I do acknowledge that there is no perfect way to compare applicants. But that's not to say that I don't think there are better ways than what people currently do. This debate is purely academic. I agree that different professors grade differently. But accounting for school rigor is a big first step to equalizing the playing field. The effect of individual professor's grading styles have much less impact than school rigor. Especially since you're being compared against the top students at a top school whereas you're only being compared against average students at an average school. Since you're still you, that affects where you will fall on a ranked curve, no matter how tough the professor grades, given that it is on a curve as most science classes are.
