How many update letters?

<p>I sent one a few days ago after being deferred SCEA. I was scared that it was getting too late. I have a few competitions coming up around March 10th (science fairs, music competitions, etc.) and I think I have a good shot at winning a few awards. Should I send a second update letter if I get these? They will just reiterate my passions, as they relate directly to a research supplement I sent them that is also being published.</p>

<p>Yes. 10 char</p>
