What are my chances of making TAMS at UNT?

<p>I received the invitation letter last year (I’m a sophomore now) and I REALLY want to make it.
I’m just really thinking I won’t.
I don’t have any of those awards everyone talks about. I don’t have a completely clean behavior record. The only thing I have is a 3.9 GPA and good test scores. I don’t even know what my SAT scores are, I haven’t taken it yet, but what scores are considered “competitive” for TAMS?
I just want to talk to someone who was accepted, or even someone who wasn’t.
I don’t even know why I recieved the initial letter. Apparently someone thinks I’m smart enough for it, but I’m worried. What are some things I need to do to increase my chances?
Thank you so much I’m so worried about this.</p>

<p>I just know that I’m not going to measure up to other applications right now and I need some advice on how to increase my chances, or what I can do to make them consider me. I’ve never wanted anything so bad, ever.</p>
