I'll add my two cents. I certainly don't have a 525 MCAT, but I applied with a <3.0GPA and a 518 MCAT.
I also wanted to say - a 3.0 is NOT a bad GPA. To everyone saying "These are the folks who are dropping out, have medical problems, are doing drugs, etc," you are just wrong. You can graduate with a 3.0GPA by consistently getting straight Bs. Yes, when viewed through the lens of Medical school, a 3.0 is very low, but compared to the general population, you're doing just fine!
For me, I chugged along at school, did the work, but I was never purely focused on the academics. I was involved with and led many demanding activities that accounted for much of my time, and were outside the academic scope. I'm what you'd call a "well-rounded" applicant.
I think I had success with my application because virtually every other aspect of my application was strong, with my MCAT leading the way. I did an actual post-bac in which I did poorly, and then a DIY post-bac (5 years later) where I got straight As in my three courses.
So I'm honestly biased, but I think a high MCAT can make up for a lot more than you give it credit for...
