URGENT!! Should Withdraw other applications?

<p>A friend of mine was accepted to a university ED. He is planning on going to that uni, has sent in his deposit, joined FB group, bought tshirts, etc. Very excited. But he is not withdrawing his other applications. He just wants to see if he gets in. I think its a bit unethical, since he is fully planning on going to this binding ED university, but I don’t think it’s against NACAC guidelines not to withdraw. However, it IS against NACAC guidelines to apply ED and then attend another university for reasons other than financial aspects.</p>
