What area in the medical field? Nursing? There are many colleges in TX with great nursing schools that you could be accepted. Texas State and UT Arlington have great nursing programs. UT Austin is out since you are not in the top 7% and A&M College Station is a reach, because they are super competitive and enrollment is primarily auto/academic admits.
With A&M, they may offer you the Blinn Team that has admission agreements for majors, where you can transfer into your major after satisfying the requirements. http://blinnteam.tamu.edu/AdmissionAgreements.aspx
A&M Corpus Christi doesn’t have SAT or ACT minimum of you are top 25% and satisfy the HS requirements http://admissions.tamucc.edu/freshman/requirements.html
There are are just too many worthy schools in Texas to list without having a specific degree in mind.
