<p>I'm thinking about writing a short letter expressing my gratitude for doing their part in admitting me into their university. I want to reassure them that it is still my first choice of college and that they will not regret ever for accepting me. Is this appropriate or somewhat too desperate?</p>
<p>I don’t think its necessary by any means but I don’t think it will look desperate at all (why would it? You are already admitted!) But, I think sending in the money to enroll would be enough, haha.</p>
<p>I don’t understand the utility in doing so…</p>
<p>^^^
Oh, reason not the need…</p>
<p>You should write thank-you letters to the teachers who wrote you recommendations for that school instead.</p>
