The most important thing you can do is to make a smooth academic transition to college. Since there is no pre-law major on this campus, you should select a major that best fits your academic strengths and interests. Contact your pre-law advisor to discuss your plans for turning law school from an idea into reality.
Start taking courses to further develop your communication skills, reading comprehension, logical reasoning and analytical skills. Select courses in your major field that interest you, challenge you, are at a level that is advanced well beyond the mere introductory, require research, and require you to express your ideas in writing. Choose a balanced and diversified course of study.
Begin to think about whom you should ask to write letters of recommendation. In most cases, you will need letters from two professors who can specifically address your academic performance and intellectual promise. Make an effort to get to know members of the faculty.
Participate in selected extracurricular activities. Your contributions and involvement should be substantive and meaningful to you. If possible, obtain leadership status and identify some way to provide service to the college and/or local community. If you need to work many hours during the school year to help with tuition, be careful to avoid letting your work commitment take precedence over your academic commitment. The same is true for other activities: school must be your top priority.
Read broadly, including some law-related materials, and talk with law students and lawyers about the nature of legal education and the profession.
