Ohio’s bar exam is similar to most state bar examinations. It has three basic components: (1) an essay portion; (2) the Multistate Bar Examination (MBE), which consists of multiple choice questions; and (3) the Multistate Performance Test (MPT), which is a closed universe writing problem. A passing score is 405 out of a maximum score of approximately 600. The MBE counts for 1/3 of the score and the written portions; the essays and the MPT count for 2/3 of the score.
In addition to passing the bar exam, the Ohio Supreme Court requires that all bar applicants have taken and passed the Multistate Professional Responsibility Examination (MPRE) before they can practice law.
There is information below on each portion of the test, as well as in the Bar Exam Logistics  page.
