<p>I have heard of some schools having days where if you go and visit the school and hand them your application they will give you an immediate decision (or a quick one within a week). This happens on specific days usually. </p>
<p>Examples: Bard (in NY) and Penn State (I think)</p>
<p>U Arkansas has “Ready Razorback” weekend which is what I think you mean. It’s on a Saturday usually (I think) and people get their admissions decision that day.</p>
<p>I don’t know if this is what you’re talking about, but it only took about 2 weeks after I applied to hear of my acceptance from Indiana University, Bloomington.</p>
<p>^ That would be rolling admissions. Immediate Decision is when you visit the campus or otherwise meet with adcom in person and they make an immediate decision on your application, results to be returned that same day or in the mail a few days later.</p>
