<p>I have already submitted a Statement of Intent to Register (SIR), and I was wondering if I should notify the other schools that I won't be attending their schools. Will this allow those on waiting lists earlier notification of their status? Or should I just not submit anything by May 1st, and assume that that means I'm not going to that school.</p>
<p>It’s very polite to notify the school. Thank then for their consideration and for having admitted you. If you have been talking with anyone from the school, like a student, professor, or alumnus/a, you may want to notify him/her, indicating your gratitude for the help in your making an informed decision.</p>
