With the Clinical Mastery Series, you can assess your understanding of the clinical sciences and evaluate your readiness for an NBME Clinical Science Subject Exam.


Self-assessments from the Clinical Mastery Series are designed for students taking an NBME Clinical Science Subject Exam. They feature multiple-choice questions on clinical science content typically covered during a clerkship or medical education course.

In addition to helping you gain a familiarity with NBME-style questions, the Clinical Mastery Series self-assessments enable you to:

  • Assess your medical knowledge or understanding of the clinical sciences
  • Target your studies using feedback that provides a breakdown of incorrectly answered questions by content category
  • View answer explanations to reinforce your knowledge and maximize study time
  • Translate your self-assessment score to an approximate score on the NBME Subject Exam score scale

The Clinical Mastery Series covers the following content areas:

  • Clinical Neurology
  • Emergency Medicine
  • Family Medicine
  • Medicine
  • Obstetrics and Gynecology
  • Pediatrics
  • Psychiatry
  • Surgery

There are multiple forms available for each of the Clinical Mastery Series content areas, with 50 multiple-choice questions per form. 

You can choose to take your self-assessment in either a standard-paced or self-paced format.

  • The standard-paced option mimics a live testing environment and gives you 1 hour and 15 minutes to complete your self-assessment.
  • The self-paced option increases this time limit to 5 hours.

Self-Assessments are delivered through the MyNBME® Examinee Portal. You must log in to MyNBME to access a self-assessment and complete it within one year. You may sign off and resume/continue your self-assessment at any time during the one-year period.

Clinical Mastery Series Self-Assessments are available for $21. Visit the How to Purchase section to learn more about purchasing a self-assessment.
