Maybe your ACT scores will be higher, as many people do better on it. With your current SAT scores, and other HS credentials, you might get an offer for Blinn Team, but full admission to TAMU is doubtful. Have you done any of the activities associated with the university, like visiting a Prospective Student Center, or Aggieland Saturday, etc? Those things are somewhat helpful. If you really want to attend TAMU, do everything you can listed on their admissions page for prospective students, retake your SAT, work hard on your essays and submit as early as possible. They do take into consideration what type of school you come from. If it's one they recognize as highly competitive, that could definitely bump you up over someone else with equal stats. But test scores are the most important. Good luck to you.
