Yes. AdaptiBar MCQ Simulator includes nearly every licensed MBE question from the National Conference of Bar Examiners, the NCBE, which is the same organization that writes the actual MBE. With AdaptiBar, you are studying with authentic questions from past exams that reflect the same form and content of those questions you will see on your upcoming MBE.
The only simulated questions in AdaptiBar currently are in Civil Procedure, the newest subject tested on the MBE starting in 2015, and Real Property, solely in the areas where the scope of certain subtopics was expanded upon beginning in February 2017.
