<p>okay, so i'm sending an arts supplement, but i don't have access to a place where i can make slides soon enough before the 31st. if my application has been sent, are colleges completely opposed if i send my supplement, say, 5 or 6 days later?</p>
<p>you need to call that college and ask if it's okay. Are you sure the application wasn't due earlier? Usually if you're sending an arts supplement, colleges set an earlier deadline from the regular deadline.</p>
