Can students appeal a rejection? Does that ever work?
There are some schools that will allow a student to appeal a rejection and others that will not, so you need to check the particular school's policy. Even if a school allows an appeal, it is difficult to succeed. You often have to show new information that was not available previously (i.e., significantly higher test scores based on a test that you just took and that the school is willing to accept) or that a mistake was made (something was inaccurate in your transcript).
