<p>Waiting list statistics are different every year. Waiting lists exist because colleges don’t know how many accepted applicants will actually enroll. It forms a buffer zone so that colleges can always get the number of students they want. Each year the number of applicants, the quality of these applicants, and the number of colleges these applicants applied to are different. There are always the possibilities that a college may accept all the people on the waiting list, or none at all.</p>
