What is the best pre-law major? A lot of people ask this question, and a lot of people are tragically misled. Most people think: “what will prepare me best” but that is the wrong question to be asking. When you pick your pre-law major you should be asking “what will set me apart and what will help me get a job.”
I think a "pre-law" major is a tragic missed opportunity. You have one shot at an undergraduate degree. In law school you will learn more law than you will need. You will have three years to study the Constitution and hone your legal logic. There is no reason to “prepare” for this three year preparation. No undergraduate major will give you an “edge” over your classmates since all of the material will be new to everyone. Use your undergraduate degree to set yourself apart and gain a skill in something in case you decide not to go to law school.
I learned this lesson when I began to look at job postings. Many of them require and undergraduate degree in the sciences or in business. A unique undergraduate degree is a great way to break in to the job market. For instance a degree in computer science could be valuable to a firm with clients in the computer business.
While I have never sat in on a law school admissions committee, I would imagine that in a pool of 50 candidates, if 49 are liberal arts majors and one is a science major, that science major will stick out much more.
Majoring in something like “pre-law” is wasting an opportunity to set yourself apart from your peers both when it comes to getting into law school and (more importantly) getting a job afterwards. I majored in philosophy, and while I more than happy with that decision (if any major prepares you for law, it is philosophy), I do wish now that I had double majored.
If you are sure that you want to major in one of the liberal arts, then do it because you love the subject, and not because you think it will pay off in law school.
