Both of my parents only went to high school too. I hope I get some sort of hookup, but I am not holding my breath. But on a couple of my interviews, they have asked about that, because I guess it is a rare thing for children of uneducated parents to attend med school. Who knows, but let's hope it can help me! 🙂
Also, I think they ask to see if either of your parents are doctors, because that may have an effect on your interest in medicine..
just my two cents...
