How can I improve? Am I competitive?

Hi guys,

This is my first post in CC so I hope it goes well. I am a rising junior as a mechanical engineer at Texas A&M. I have a fairly decent amount of questions to ask. Based on y’alls opinion, is TAMU competitive for engineering? I’ve gotten so many mixed reviews that I wouldnt mind a solid answer. Additionally, I would really like to go to Georgia Tech, Stanford or Ann Arbor for Aerospace or Mechanical engineering. However, I currently have a 3.55 with some honors classes like thermo. I had an honor research project in which I made a simple model of the human arterial system and I am an undergraduate research assistant in a materials science lab. Despite all this, I still feel pretty inadequate and I fear I am not doing enough to better myself and be competitive. How can i improve myself and how competitive am i right now? Thank you all.
