So that means unless your MCAT is out of the ballpark (and realistically with 3.33 you have to take a ruthless assessment of your test taking skills), your GPA is going to be a hindrance even if you take those classes and ace them (and again, you should have a realistic expectation of why you would do better now than in the past). Unless you've got something "special" you're leaving out (military service, research, URM status, etc) you should focus on D.O. schools. Rushing the process for either application is often a lethal mistake as well. If you've always wanted to do it, 1 more year of "not doing" it is not that important when weighed against submitting the absolute best application you can the first time.
