Sending a letter off to colleges updating

<p>Hello parents!
I'm sure all of you have a great deal of knowledge when it comes to the college process.</p>

<p>Would it be advisable to send each college I applied to a letter of update, explaining what awards I have won, and things I have accomplished since I sent in my applications?</p>

<p>Also, would it be alright if I sent a letter to a college explaining how it is definitely my first choice?</p>

<p>help!</p>
