Deffering Admission & Applying To Another School

<p>I was accepted to a school for the spring semester; its not really my top choice school and I wanted to apply to couple of schools that are better for me. I was wondering whether it was possible for me to defer admission to the fall semester and also apply to a couple of schools and if I do get into my top choice, then I can turn down the school I got into and go to the other school.</p>
