Do physics majors go to law school? Yes, and they do well on the Law School Admissions Test (LSAT).
The Law School Admissions Council (LSAC) compiles LSAT results for different majors, and occasionally an organization like the American Institute of Physics or US News and World Report will share those results.
Here are the top 10 majors ranked by “Mean Highest LSAT” for students that applied for admission to law school for the 2016-17 academic year. Three of the top four have the word “physics” in them.
The number of physics majors applying to law school is relatively small – more than 12,000 political science majors applied for entry in the 2016-17 academic year (and their Mean Highest LSAT score was 153.80).
Below is the spreadsheet that I downloaded from LSAC so that you can tinker with it and see how different majors do in the law school admissions process.
