Recommandation letters and Common App

<p>If i obtain 3 recommandation letters from my academic teachers
and put them up on common app</p>

<p>they can be forwarded to ALL colleges i have selected?
or only 1 college (ie, i need to get completely different letters for different colleges)?</p>

<p>The teacher or counselor has to upload it themselves electronically (or they can snail mail it to each individual college). Once the teacher or counselor uploads the letter to the Common App, you can't read it, but you can select what colleges to send it to - just one, a few, or all colleges you're applying to.</p>
