Ultimately, SDN is just a bunch of people talking over the Internet. If you apply, it will cost you only time and money, and the bruises to your ego that stem from rejection. You're not going to damage yourself by applying to LUCOM and the other DO schools that tend to be more forgiving on the MCAT.
From an adcom's perspective, a person with a 24 shouldn't be admitted, because them failing Step 1 would damage the school's reputation. (can't DO students take COMLEX instead of USMLE? What are the pass rates for that for someone with a 24?) Adcoms are risk-averse and have the privilege of selecting from the best applicants. From a student's perspective, a 10% chance of them failing Step 1 probably doesn't have a big deterrent effect.
There are three outcomes here: either the student gets rejected and finds a new career, or the student gets accepted and passes Step 1 and lives happily ever after, or the Catastrophic Bad Outcome of the student getting accepted and failing Step 1 and being saddled with massive debt and no marketable skills. The Catastrophic Bad Outcome is exceedingly unlikely, occurring probably only about 2% of the time, with the most likely outcome being simple rejection. I suggest the student applies next cycle (getting a bit late for this one) one last time just to get any regrets that may arise down the road out of the way. It's better to try and fail than to give up and live the rest of your life regretting not even trying.
OK, you make good points. But why not allow the OP to consider what in the world is wrong with them, if possible, and if indeed they can fix it? After doing due diligence, which I concede, the OP should have done before taking the MCAT a second or third time, it is then that she will need to firmly face finding a new career. If she indeed has text anxiety amenable to remedy, it may be worth it to try again. It depends, and only she along with some WISE counsel, can determine this.
Being "in good shape" for Step 1 is not just barely passing Step 1. You know how bad a very low Step 1 score looks? So bad that it would almost be preferable to actually fail it so they can get help, correct their deficits, and try for a solid score on the second time around, even though most programs in certain fields don't even consider applicants with more than one Step 1 attempt. The goal is to get a solid Step 1 score so that you can open doors or keep doors open so that you can be competitive for whatever you want to go into. Just because you're going for IM and not derm doesn't mean you're "successful" with a 220. You're probably thinking of "success" as "matching, no matter in what or where as long as I'll be a doctor" when there's really a lot more to it than that. That's something I didn't fully understand as a 1st/2nd year med student, certainly something I don't expect a pre-med to fully understand yet. That one number alone can close a heck of a lot of doors.
