Retake the mcat before matriculation. If its solid for MD, dont attend a DO school. If its just to attend an “established DO school”screw it. Just get through ASAP. I had to defer starting a year after my acceptances bc of unforeseen circumstances. That year cost me a year of attending salary and now I’m competing against a couple hundred more DO applicants. Being at an older school just means the powerpoints are older and for some reason on SDN that matters...
If you aren’t ok with the specialties mentioned above, don’t go DO. Go PA, finish in the bottom of your class, and work in ortho/CT surg/ER/derm, etc.
Only an MD-level increase in mcat warrants a year delay.
