So you've been accepted to UCLA, USC, Loyola, Pepperdine, Southwestern, and Whittier all with full scholarships. And while you're still trying to make your final decision, you know you wont go to Pepperdine for sure. Give your spot back ASAP. There are people on the waiting lists at EVERY school regardless of its ranking. Those students want and need you to say thanks but no thanks.
Maybe that's a little dramatic but seriously, it's unethical to hold spots at schools that you KNOW you wont attend. Let the schools know ASAP that you wont be joining them in the Fall so they can give the spot to someone else.
Do your part for humanity and make some waiting student's day a little brighter.
