Question:

What resources are available to prepare for the examination?

Answer:

No test preparation courses are affiliated with or sanctioned by the NBME or AAOMS. The best preparation for the CBSE is a general, thorough review of the content reflected in the examination descriptions. You may also practice for the exam by taking an NBME web-based self-assessment to evaluate your readiness to take the CBSE. The Comprehensive Basic Science Self-Assessment (CBSSA) uses multiple-choice items based on information typically covered during basic science medical education courses. Participants will receive a performance profile and a score interpretation guide immediately after completing a self-assessment. The performance profile provides an assessment score and graphically displays relative strengths and weaknesses in general topic areas.
