<p>Best major will be whatever you will find most interesting to you, which will help you get the best grades possible. Law school admission is all about GPA and LSAT. Once you are in law school, you will learn all you need to determine which legal areas you like best. Corporate lawyers do many things (contracts, litigation, patents, defense, labor, etc.), not all of which require advanced business education. I personally know corporate lawyers who majored in finance, accounting, poly sci, engineering, psych, philosophy, and English.</p>
