I got into 2 MD programs with a 506 and a 125 on CARS (it was my lowest section). I was also from the south tho and had a high GPA. A 3.8 or 3.9 GPA with a 505 could get you some love from your state schools or other low tier schools depending on what region you live in.
I had a little bit of everything, not nearly as much as what I see people posting about on here. I was passionate and genuine in everything I did and I think that was evident to people that reviewed my app. That is much more Important than collecting hours
