After your LSAT score and GPA, the personal statement may be the most important part of your application. So, what is it? An admission dean suggested to think about it as a serious knock-knock joke. "Knock-knock" "Who's there?" Now answer that question. The statement gives you an opportunity to let the law school who you are and what you bring to them. They also want to know why you are a good fit to their program. This should cover material that isn't found elsewhere in your application. Be sure, however, to read the application carefully and frame the statement around the topics and questions they ask.
As always, see the pre-law advisor for more information.
