Good Idea: Update letter?

<p>Would it be a good idea to send an update letter to my top two schools? I'm thinking of something informal just to inform them of some things I've done in the past months, why the school is a fit and that I'm very interested? Or is that just a waste of time. Thoughts? This would be for Brown and WashU.</p>

<p>Um as in certain awards I've recieved and accomplishments I've had recently. Sorry if that needed clarification.</p>

<p>I don't think it's a dumb idea.
Just be careful with the length. Be brief, straight-to-the-point =)</p>
