<p>My friend did this, and said it's better to send it one at a time then all at once. How do I do this? I don't want to erase all the supplements I did.</p>
<p>Well, what you could do is duplicate the applications on the website after sending to one, and keep doing it for each school..although I don't know why it's better to send them one by one provided the info is accurate/complete. As for the supplements you could just copy-paste the ones you already have.</p>
<p>Just remove all the schools from "My Colleges" except the one you want to submit it to. Commonapp doesn't erase the supplement data, so when you add back the schools you removed, your supplement stuff should be there.</p>
