I don't think it's a mistake at all -- thought it does take guts!
Think about it -- Your stats are very good. In line with the 90-10 margins of probably every school in the state, right? So you've got 8 high quality medical schools with cheap tuition who are already biased in your favor. Even applying to 30 schools, how many pre-meds have 8 really good fit schools that they'd actually want to go to? (Maybe you'd prefer some TX schools over others, but wouldn't you prefer *any* TX school over one that costs $250,000 more?)
Assuming you have no red flags and your PS doesn't suck, you should expect at least four or five interviews, very possibly more. And if you don't suck at interviewing, you can reasonably expect a several offers. And with TX's match, the odds that at least one school will be willing to accept you are really quite high. So that's the good news.
The bad news is that if you do have red flags, if your PS does suck, if your ECs are lousy, and if you interview poorly, you may not get in. Explain how that will change OOS? Will you somehow be more competitive there?
So my advice for Texas applicants is:
- If you're a stellar applicant, apply to your dream schools. You might get in.
- If you're an average to good applicant, TX is a great fit. The circumstances in which you would not get accepted anywhere in TX but would get accepted somewhere else are, uh, what?...
- If you're a below average applicant, your OOS 'safeties' should be DO. See 'average' above.
