Tideguy,
A returning student is one who left and then came back--like me!! I left college without a degree to pursue a bike racing career. I raced full time for 5 years, then came back to school, changed my major from poli-sci (dont ask) to bio, and got to work on my GPA--Which was 2.8!!! I'll be graduating in Dec, but even with (almost) straight As since my return, my GPA is still MUCH lower than yours, because I had so many credits from before! I'm counting on my "upward trend" and solid MCAT to see me through. Your GPA of 3.6 seems like cake to me in comparison. Also, if you have a good upward trend in your GPA, that should help too. Your probably applying to more prestigious schools than me, but still I think you're sitting pretty--Good luck 😀 !!!
