You may feel like you've lost a chance, but truthfully, you've gained an opportunity. You have a whole year to strengthen your application, grow as a person, experience life outside academics, and enjoy spending time with your friends and family. Make the most of this time in every way. When all is said and done, you might not only find that you enjoyed yourself greatly, but that the experiences of the last year had a long lasting and positive impact both on your application and on you as a person.
