absolutely! this is one of the main differences between admission standards at allop. vs. osteop. schools. DO schools tend to look favorably on people who actually show some dedication to the medical profession rather than what your gpa is. that's not to say grades and mcat scores are not important but they're not the main determinant for admissions. but remember you should always try to make yourself the best possible candidate you can. that means if you have a low mcat score and you know you can do better, than i'd go ahead and take the test again. it just makes you stronger in the long run.
