Not ALL DO schools are that low those states/schools you mentioned are a few programs--same happens for MD schools. I guess that is why people apply broadly. Gotta get in where you fit in. Here's a link to compare averages, some MD schools, actually, a lot are in par with many DO schools average for anyone who is curious:

To the OP: Yes some schools state the min. req. to get a secondary is a 2.75, but if anyone has gotten in with that low of a GPA, consider yourself lucky. It is not the norm. They have no problem taking your money for a secondary with such a low GPA and rejecting your butt soon after. I interviewed at my State MD school whose minimum to apply was a 3.2 and a 22 MCAT BUT the average matriculants stats were much highter, 3.6+ and 30
MCAT. Take minimums with a grain of salt. With a 3.2 gpa and a good MCAT score, there shouldn't be much of a problem if everything else is straight.
But I'm gonna have to agree with some of the other posters, I'm not sure you really know what you want in the medical field.
One more thing, a friend gave me practice PCAT book along with some other MCAT materials and I'm not trying to bash the PCAT but from what I saw, I would take that test over the MCAT anyday.
