But if you don't want to work in this direction, you don't need to take the exam.
My little advice-
First: if you major in law, you should take the judicial examination.
Second: If you are interested in law and law, you can study law and legal books after class.
Third: Law is closely related to life. If you have time, you can look at relevant cases to know what legal knowledge you need.
Fourth: the requirements of the judicial examination are not strict, provided that you are ready to take the examination yourself, so that you can pass the departmental examination.
In a word: I think you should learn this major well.
