I'm 44, so my guess was an average of 29 before I saw that PDF link. But I saw it several months ago, so it's possible that I remembered it. Although I also took both FAR and REG not too long ago, which I credit for my horrible memory for pretty much anything else these days. 😐

I'm 33 and I just passed the entire exam as of yesterday. Ten years in the Air Force, came home and went to college/grad school, graduated in May, passed exam over summer, first day at the big4 in two weeks.
I am 34. I had my family first and went to work in industry right out of college. I wasn't sure I wanted to be a CPA (I was a financial analyst for quite a while) but life changes and so do priorities. Now, I'm working in public and after 12 years of being out of school, I'm trying to knock the exam out.
