Welcome to the forums.
Please follow the WAMC template. Your experience details are important, not just the hours. Maybe some more shadowing (get closer to 50 hours).
If you know your MCAT is holding you back from a shot at the brand-name schools, why are you taking the shot? You can always get your residency training at brand-name schools or their affiliated hospitals.
You are in prime position for the top Texas in-state programs, details pending. Is there a reason why you wouldn't go to UTSW, Long, TxA&M, or any other Texas school?
