He will be rolling the dice, especially if he does not take his essays and EC resume very seriously. This year I estimate based on reported applications and past admissions that a review candidate had about a one in 4 chance of admission ( including Blinn, & Gateway). If you read the long thread that covers the last few years with the TAMU admissions heading, you will note that there are many students who are almost top 10% and or almost academic on test scores that are very disappointed when someone they know that had lower scores / lower rank got in and they did not. If you are in review, there is a lot of competition and you must stand out from a very talented crowd to be admitted. There is a very telling quote in there that says something like realize you (the applicant) are all alike- competitive high school, strong test scores, solid rank, strong ECs. Auto admit and academic take most of the spots.
