Where for ED?

<p>Say I have a 15% chance of getting into College X and a 30% chance of getting into College Y. I prefer x to y though I would be very happy at both of them. Should I go for ED at college X and boots my chances to 25% or go for ED at College Y and boost my chances to 40%?</p>

<p>Whichever you like more.</p>

<p>Isn't it too late for ED? Or is this for ED II?</p>
