When it comes to law, there are many areas in which one can find expertise. These include, general legalities, legal departments, insurance, medical, health and disabilities, among others. So, if one is interested in a career in the legal field, one may want to consider the area one plans on practicing.
For, often one must declare both a major and a field of expertise when applying to law school. As such, whether one is interested in working in the legal department of a corporation or as an attorney, one may want to focus on the more legal aspects. For, when one works inside a corporation, often one works more with documentation than people.
Of course, one can retake such a test after a certain amount of time. As such, one can study independently as much as possible between the first and second test in order to have a better chance of passing the next time. However, as not all jobs within the legal field require such a test, one can also opt to find such a position either between tests, or if one does not wish to retake such test.
