The Multistate Bar Examination (MBE) portion of the exam accounts for 50% of the total score and is a nationally administered, 200-question multiple choice exam. As of February 2007, only 190 questions are scored, and the other 10 are unscored experimental questions used to gauge their appropriateness for future exams. The MBE covers only the topics of contracts (including sales of goods under Article 2 of the Uniform Commercial Code), real property, torts, constitutional law, criminal law and procedure, the Federal Rules of Evidence, and the Federal Rules of Civil Procedure. While the essay section of the exam may test one or more of these areas as well, the MBE section is dedicated to these subjects.
