Along with years of dedication, studying and preparation, certain careers require minimum passing scores on tests necessary to be successful in that profession. These exams are often labeled "high stakes tests" due to their "all or nothing nature": if you don't pass the test, you can't get the job you had dreamed of. Lawyers have to pass the bar exam. Accountants have to take the Series 7. There are high stakes tests to become a career diplomat at the State Department. Special forces branches within the military have tests. Elite colleges and universities have minimum scores for both undergraduate and graduate admissions based upon the SAT and GMAT exams. None of these exams are easy, but that is the point. Professionals within the industry know what specific domain knowledge it will take in order to be successful in that field. If you can't pass the test, it might not be the best match for your career.
