Clarity vs Mark Klimek for NCLEX-RN prep
Mark Klimek is famous in nursing student circles for his 12-lecture NCLEX review series — many graduates listen to them in the final week before the test. Clarity is a 5,000+ question adaptive bank with NGN case studies, AI tutor, and timed readiness exams. They solve different parts of the prep problem and many students use both.
Mark Klimek at a glance
Mark Klimek is a long-time nursing educator who recorded 12 audio lectures covering high-yield NCLEX content. The lectures focus on mnemonics, fast pattern recognition, and "Klimek rules" for prioritization, lab values, acid-base, and drug safety.
The lectures are sold through ReMar Nurse Live and other distributors, typically as a one-time purchase. There is no question bank, no adaptive practice, no NGN item types — it's pure audio content review.

When Mark Klimek wins
Klimek's lectures are unbeatable for the last 7–10 days before the test. They consolidate content into memorable rules ("when in doubt, pick the silly one for psych questions") that stick in the moment of testing. If you learn auditorily, like while commuting or doing chores, the lectures deliver more per minute than reading a textbook chapter.
When Clarity wins
Practice volume is the single strongest predictor of first-attempt NCLEX-RN pass rates. Klimek alone doesn't give you reps. Clarity gives you 5,000+ NCLEX questions, real NGN case studies, partial-credit SATA scoring, an AI tutor that walks you through misses in plain English, and timed readiness exams that simulate the actual adaptive test.
Klimek's lectures predate the 2023 NGN format. The mnemonics still work; the format doesn't. You need NGN practice somewhere, and Clarity is the cheapest option that delivers it ($9.99/mo vs UWorld's $109).
The combo most students use
Listen to Mark Klimek's lectures during your final week as a high-yield content review. Use Clarity (or UWorld/Kaplan) for daily question practice during the 6–8 weeks of focused prep before that. The two are complements, not substitutes.
Bottom line
Mark Klimek and Clarity solve different problems. Klimek = passive content review and mnemonics. Clarity = active practice, NGN exposure, and adaptive readiness. The highest-passing students use both. If you can only pick one, pick the one that fixes your bigger gap: knowledge (Klimek) or test-taking practice (Clarity).
