do you need a college degree to take the bar
In the US, most states require that you have a JD degree from an accredited law school in order to take the state bar exam for admission to practice law. And, to attend an accredited law school, you must generally have a bachelor's degree from an accredited undergraduate institution. The only specific bar exam of which I'm aware is the patent bar exam, for which you must additionally have a degree in an approved hard science in addition to a JD.
