Class ranking and GPA only really matter when first applying to the residencies that you will rotate through your 4th year. And in most cases you don't need an amazing GPA to get the opportunity to do a 4th year rotation with the residencies that you want. Once you rotate with the residency programs your 4th year all they care about is if they like you, GPA and class ranking becomes minimal at that point. So.... I would say if you have a low GPA and class rank show them how great you are in a clinical setting and that you can work hard and are easy to teach. That is one of the great things about podiatry school compared to MD and DO, pod school is much more forgiving when it comes to messing up grades, in the end it's mainly about your personal/team based skills and work ethic.
And for those of you who don't know, the general 4 year layout for pod school is 2 years of studying for boards 1. 3rd year you rotate through local clinics to get a hang of working in a clinical setting, and then 4th year you'll rotate through a whole bunch of residencies for about a month each. at the end of 4th year you'll interview with the residences who liked you. You rank your top residencies and the residencies rank their top students. "The system" then matches the students and the residency programs and everyone is happy. Unless you scramble which means you don't rank with the program you wanted and some programs don't rank with the students that they wanted. You all then have a few days to all find each other and match one with another, scrambled with scrambled (this whole scramble situation is actually pretty low and won't happen if you aren't incredibly picky, but that's a discussion for another thread).
