If you aspire to become a nurse, passing the NCLEX exam is a crucial step before starting your career in the field. The NCLEX exam, whether for Registered Nurses (NCLEX-RN) or Registered Practicing Nurses (NCLEX-PN), is a nationally recognized exam administered by the National Board of Nursing (NCSBN). State nursing boards use NCLEX scores to determine a candidate's eligibility for a nursing license.
