Arts Supplement questions - please help!

<p>I'm applying to a school that has an Arts Supplement deadline of 12/20...what would happen if I mailed everything the day after, on 12/21? Would they not accept the supplement (or worse, would it reflect badly on my application overall)? Because for various reasons (i.e. my music teacher hasn't given me the CD yet, and I've been snowed in), I've missed my chance to get everything to the post office in time...and sending things electronically just seems to have too many potential pitfalls. Would it be ok if I just mailed everything on the 21st? :&lt;/p>

<p>Another question: many of the schools I’m applying to asked for a music teacher recommendation along with the rest of the arts supplement. Since I am sending both a piano and a violin arts supplement, I asked both my piano and violin teacher to write recommendations. I thought this was required, but now it seems a bit excessive (esp. since my violin recording is only good, not stellar). IS that excessive? Or is it ok</p>
