Assess your chances realistically. While it's always a good idea to submit an application to a top law school if you have some chance of success, there's no point in wasting your time in preparing an application to a school that would never accept you because of your insufficiently stellar academic record. There are still many law schools that you may be able to get into. If you have some time to spare, prepare for your exams and read law literature. Research the law schools you are applying to. Some second-tier schools may have first-tier programs or concentrations. Apply to enter these programs.
Some applicants underestimate the importance of a personal statement. While a personal statement alone will not guarantee the success of your application, it can make your application stand out from the applications of other students. Tell admissions officers what is important to you, what your values are and what influenced your life. Be concise. Also, give the reason why you chose to apply to this particular law school.
When choosing a professor to write you a letter of recommendation, select people who know you well over scholars holding a respectable title. Also, avoid recommendations form persons who may be regarded as having a bias, such as relatives.
Your application should be complete. Do not omit any important details about yourself or provide false information. Also, do not include irrelevant information. For instance, don't mention that you write books unless they are good enough to be published.
