I think my GPA is my biggest weakness but hope that it can be offset by my GMAT. I was a bit too focused on being top dog in college, hence my involvement (and having a bunch of fraternity/leadership awards) and just didn't put the time into my classes. My post-college employer is decently known in the economic community but otherwise not a strong name. The research center I currently work with is affiliated with a few top academic institutions (including ivy league) but not sure how much that will help. I've enjoyed helping my bosses at work past my normal duties, especially in improving efficiency in managing budgets and general financial processes. I'm hoping to move into consulting with an MBA.

I have a few friends from college with much weaker stats and work experience that ended up at schools ranked between 15-25, so curious if I have a better shot at other schools.
