Respiratory Review Workshops, Inc., also referred to as The Persing Review, believes that the best way to prepare for the NBRC credentialing exams is by practicing exam questions and discussing the material related to each question. This workshop is very detailed and reviews material from all content areas of the NBRC TMC Exam Content Outline. One hundred and ninety-five NBRC-like questions are administered in 10 exams that are grouped in sections according to the content outline assuring that all areas of the exam will be reviewed.  Practice clinical simulations will also be completed and reviewed in detail.

The Persing Review is a comprehensive 2-day workshop to help review individuals for both the TMC Exam and Clinical Simulation Exam.
