<p>Staying on the waitlist is free, and doesn't need to take much psychic energy. Send in the cards with a "yes" to the waitlist schools and consider them like a lottery card (chances are small that you will get it, but it is always a possibility) - then concentrate on the admitted schools. If you are accepted off the waitlist - great! If not, well, you have been concentrating on the schools you were admitted to.</p>
