info/advice on changing first choice school for NMS now

<p>So, I put in my first choice as UPitt before March 1.</p>

<p>Today, I find out that they will only pick 3 people for it and it will be $1,000.</p>

<p>I want to switch it to WashU, but what is the deal now since it’s after March 1?</p>

<p>thankss</p>
