AdaptiBar's MBE Simulator program provides you with two MBE Study Aid Exams comprised of the NCBE's newest released questions, and many users wish to exclude these questions when in Practice Questions mode. This allows them to simulate an MBE of just these licensed questions in Practice Exams mode, with the reassurance that they have yet to answer those questions.
If you wish to reserve these questions while in Practice Questions mode, make sure the checkbox next to “Exclude MBE Study Aid Questions” is selected.
NOTE: If you do wish for the algorithm to present you with these questions, make sure you keep this feature turned off. If the box remains checked, you will begin to see repeat questions before you have exhausted all questions within a particular subject.
