Should I even bother w/ this mistake?

<p>On my common app, on additional informations, I forgot to list that i was in a gifted program for math and science for half of tenth grade (i moved).
The course was REALLY hard and actually caused my grade to drop almost 10 percent...</p>

<p>Should i email them? Or send them a letter?
But i'd feel stupid if i just sent them a small letter, and was like </p>

<p>"Err... i forgot to tell you but. I was in a gifted program in sophomore year..."</p>

<p>Thanks in advance! :)</p>

<p>I would not bother. If it's important and you failed to mention it before, you appear sloppy. If it's not important and you send them a small letter, you appear overanxious. Either way, you don't look good.</p>

<p><em>sigh</em>
you're right. I guess i just gotta suck it up :'(
ah well, it's just ONE school. I'll change it for the other ones. :(:(:(</p>

<p>Thank you very much for your feedback though :)
very helpful</p>
