Bad, bad, bad advice. You haven't even taken the MCAT yet, stop giving ****ty advice. I was a triple reapplicant. It is an uphill battle. Reapps are not given a red carpet. Check all the posts about depression/discouragement in the reapp subforum. Every time you reapply, you need at least one new LOR and need to have accomplished something that says 'I'm a better candidate than last year'. If your app is the same, it gets tossed in the trash. And yes, they do compare your current app to previous cycle apps.
Unless you have some secret weapon you aren't sharing with us, I do not think it is worth it. Work on your GPA, rock the MCAT, and do ****. Reapply next year. DO is a strong shot; MD is a long shot. You could probably get an MD interview or two, but you may get zero (I got 1 with a 3.3 and a balanced 33 MCAT). My first cycle, I applied late (roughly sept) and got zero interviews. Second cycle, I had no real improvement, but I did apply on time - zero interviews. Third cycle, I did an SMP (which I did very well in). I got 1 interview before grades were sent out (waitlist). After they got sent out, I got 2 more interviews and was waiting to hear back from a third school for an interview. I got an acceptance to my SMP's med school, so I withdrew from everything else.
Apply early (submit primary in June, you'll get secondaries late July to early August, get them all submitted within a week or so of receiving the secondary. Ignore the 'deadlines' the give you, if you submit the secondaries in sept/oct/nov/dec, you are sabotaging yourself) and schedule your interviews to the earliest date you are offered if possible. The earlier you get **** done, the better your chances. The difference for primary app submission between June 10th and June 20th is tiny, but it's a slippery slope. Show some discipline.
You're 25. The average age of entry to med school is 24. If you matriculate at 26, boo hoo. It doesn't matter. A lot of your class will be your age. By the time you start residency, you'll be 30. There will be many 30 year old residents beside you. Who cares? If you waste a cycle, you will flush money down the drain, and lower your chances in the future. Would you prefer to matriculate at 27?
