I wouldn't worry ... I scored a 23, 21, and 27 with a 3.5 CumGPA and 3.6 SciGPA and still got into two DO schools (didn't bother finishing 2ndaries for others once I knew I got in) . The key is to APPLY EARLY, show high interest in the schools (by going to open houses and meeting admission reps) and have solid EC's/letters. Some schools appreciate a high upward trend.
