For those of you asking about scholarships from UM, about 25% of the incoming class will get one (ranging from $5-35k per year). Most of those are given out a merit basis, with a few given out on a need basis. All are awarded at time of admission and renewable for 4 years, and thus are fixed (including need-based awards, which are not reviewed on a yearly basis). Most of the merit-based awards are given out to people with GPA and MCAT scores above the accepted average, but it's not a perfect correlation.
Also, for those of you complaining about high tuition costs and high interest rates, as an Economics major in undergrad I can tell you that med schools are simply behaving rationally as any profit-maximizing business would do: charge as high as they can until market supply is in equilibrium with demand. But the same time, as a rational consumer, you should have the ability to decide based what options you have and if it's worth it to pay the price for what you're offered. For med schools, they all know that even now, physicians from American med schools still have a good chance of making a reasonably decent profit in the future, and thus that's why you get ~5% acceptance rates at med schools across the country even with the high tuition, high interest rates, and high application costs that you must pay. In contrast, for example, PhD programs will almost always PAY for their students to do the PhD and pay for all interview costs during the application process, and even then the application process to get a PhD is not nearly as competitive. Why? Because the future expected earnings of a PhD degree are currently much lower than that of an MD. So the bottom line is: if the financial cost of something is outside what you have or are willing to spend, then don't go for it and complain.
