Hey,
As one of the authors of the "Master's Guide" I would like to address some of the questions that students have raised regarding our material. First and foremost, we have gone to great lengths to make sure that our questions do not violate the copyright regulations of the NBOME. Our questions are designed to prepare students for the COMLEX I and if used appropriately should raise your score by 50-70 points, based on student reviews. We price the material based on the stipends given to our questions writers and the costs of production. We try to write our questions in a way that will give students a quick and bulleted review of the most high-yield information in a format that is specific to the COMLEX. Please feel free to contact us with any questions you may have regarding this material. Good luck to everyone in your board preparation.
