<p>I would say at best your chances are 50%. Anything engineering is really difficult esp. at TAMU. Since you are not in the top 10% that really hurts and your SATs could be higher but they aren’t awful. Did you send both SAT and ACT? I understand your desire to go to TAMU, but I know Oklahoma State has an amazing Petroleum Engineering program with higher acceptance rates.
And there is always the chance you can be accepted and later switch into engineering.</p>
