I applied to several DO schools (all supplementaries in) around the first week of December. I have 2 science, 1 research PI, 1 boss, 1 non-science, 2 MD, 1 DPM letters all part of my composite. I am shadowing 2-3 DOs this month and hope to get a letter. My GPA is a 3.661 (science about 3.47) with a double major and in the honors program. 26 MCAT. I have a lot of extracurricular and shadowing experience. What are my chances of getting in this cycle? Should I start studying for the new MCAT instead of waiting around?
