Mark K NCLEX: Free Lectures, Audio Files, & Study Strategy

If you have spent more than ten minutes inside an NCLEX prep forum, you have already heard the name. Mark Klimek, almost always shortened to Mark K, is the live-review instructor whose voice has guided more than a million nursing graduates through their last weeks before the exam. He is not a content creator chasing trends. He is a clinical educator who has been teaching the same condensed three-day NCLEX review since the late 1980s, refining it lecture by lecture, classroom by classroom.

What makes Mark K different is not the volume of content — his materials are shorter than most full review books — it is the structure. He teaches you how to think through an NCLEX question, not just what to memorize. His students walk in with thick stacks of flashcards and walk out with a handful of mnemonics, a handful of decision rules, and a calmer set of nerves. That shift in mindset is exactly what the test rewards.

This guide walks through everything you need to know about using Mark K effectively. We will cover the official audio lectures, the free YouTube uploads, his signature mnemonics like the alphabet game for select-all-that-apply and A-E-I-O-U for endocrine disorders, and how to combine his teaching with the question banks you already own — UWorld, NRSNG, Saunders, or Kaplan. You will also see why his style works especially well for visual and auditory learners, and why most successful test-takers reserve him for the final stretch rather than the early review weeks.

By the end you will know whether Mark K should be the spine of your study plan or a supplement layered on top, and you will have a clear three-week roadmap to follow. Whether you are sitting for the NCLEX-RN, the NCLEX-PN, or a re-take after a previous attempt, the principles are the same. Quick test of where you stand right now?

Who Is Mark Klimek?

Mark Klimek is a registered nurse, a former hospital educator, and the lead instructor at Hurst Review and later at independent live courses. He built his teaching reputation in the era before YouTube, traveling to nursing schools and hospital systems to deliver three-day live reviews. Those reviews were recorded onto cassette tape, then CD, and eventually digital audio. The 12-tape series most students refer to is a near-verbatim capture of one of those live weekends.

What set him apart even thirty years ago was his refusal to teach the way textbooks teach. Mark K argues that the NCLEX is not testing your knowledge of pathophysiology — it is testing your ability to prioritize, delegate, and make safe clinical judgments under pressure. So his lectures are organized around question-answering frameworks, not body systems. A typical Mark K segment might spend forty minutes on how to read a select-all-that-apply stem and only ten minutes on the actual content the question references.

His style is conversational, sometimes blunt, and full of repetition. He will say a rule three different ways in three minutes because he knows that one of those phrasings will be the one that sticks. Students either love him for it or find him too informal — there is rarely a middle ground. The pass-rate data, though, is hard to argue with. Schools that incorporate his audio into their NCLEX prep regularly report first-attempt pass rates well above the national average.

He is now in his seventies and still teaches live cohorts a few times a year. Most students, however, encounter him through recordings — and that is where the rest of this guide focuses.

The Official 12-Tape Audio Series

The Mark K audio lectures most students reference are sold through NursingExamCram and a handful of authorized resellers. The series is twelve tapes long, roughly nine to ten hours of total audio, and it is split into a logical progression rather than alphabetical order. You start with acid-base, move into endocrine, work through cardiac and respiratory, then finish with psych, pediatrics, and OB.

Each tape is around forty-five minutes — short enough to play on a commute, long enough to develop a real idea. Mark K opens almost every tape with a quick re-cap of a rule from the previous one. That repetition is intentional. By tape twelve you have heard the alphabet game described seven or eight times in different contexts, and it has become second nature.

Here is the rough order students follow:

• Tape 1: Acid-base balance and the ROME / MURDER mnemonics
• Tape 2: Ventilators, chest tubes, and respiratory priorities
• Tape 3: Endocrine — the A-E-I-O-U framework
• Tape 4: Cardiac rhythms and the "lethal" priority rules
• Tape 5: Psych medications and crisis response
• Tape 6: Maternity and the "FHR before BP" rule
• Tape 7: Pediatrics and developmental milestones
• Tape 8: Delegation, prioritization, and the LPN-vs-RN split
• Tape 9: Lab values you actually need to know
• Tape 10: Pharmacology shortcuts and suffix rules
• Tape 11: Select-all-that-apply strategy
• Tape 12: The "miscellaneous" tape — wrap-up rules

Some students listen straight through over a weekend. Others spread the series across three weeks and pair each tape with a corresponding chunk of practice questions. The second approach is what most high-scorers describe.

Free Mark K Lectures on YouTube

You can find a near-complete version of the 12-tape series on YouTube, uploaded over the years by former students and a handful of channels dedicated to NCLEX prep. The audio quality varies — some uploads are clean digital captures, others are slightly muffled rips from old CDs — but the content is the same lectures sold commercially.

Whether you use the free version or pay for the official audio is a personal call. The arguments for paying are straightforward. You get clean audio, a guaranteed full series, downloadable files you can keep on your phone without buffering, and you support the instructor who built the material. The arguments for the free route are equally clear: nursing school is expensive, you may only need the lectures for two weeks, and the content is identical.

If you go the YouTube route, search for "Mark Klimek Lecture 1" and check the upload date. The most-watched uploads tend to be the cleanest. Build a playlist in order so you can autoplay through your commute or while folding laundry. The lectures do not require visual attention — Mark K is intentionally audio-friendly because he was lecturing live, not showing slides.

One caveat. A few uploaders have re-cut the lectures into shorter segments by topic, which sounds convenient but actually breaks the flow. Mark K teaches by digression. A "tangent" in the middle of the endocrine tape is often where the most useful rule lives. If you only listen to the trimmed highlight reels, you will miss those moments. Stick to the full forty-five-minute versions whenever you can.

Mark K's Signature Mnemonics

The reason people remember Mark K lectures years after the exam is the mnemonics. He is a believer in turning every rule into something short, slightly absurd, and easy to recall under pressure. Two of his most famous frameworks deserve a closer look.

The Alphabet Game (for SATA)

Select-all-that-apply questions are where most NCLEX test-takers lose points. The traditional advice — "treat each option as a separate true-false question" — is fine but slow. Mark K's alphabet game adds structure. You read option A. If you are not certain it is correct, you skip it. You read option B. Same rule.

By the time you reach option E, you have only marked the ones you would defend out loud. The result is a clean, consistent approach that prevents the "I think four of these are right, so I'll guess on the fifth" trap. It also tells you to slow down: SATA items deserve more time than single-answer items, and the alphabet game forces that pacing.

A-E-I-O-U for Endocrine

Endocrine is one of the highest-yield topics on the NCLEX, and one of the most confused. Mark K's A-E-I-O-U framework keeps the major disorders straight. A stands for Addison's (adrenal insufficiency — low everything). E for the opposite, Cushing's (excess cortisol — high everything). I for inappropriate ADH (SIADH — too much water retention). O for the opposite, diabetes insipidus (too little ADH — too much urine). U ties them together with the question to ask first: "Is this patient holding fluid or losing it?" Once you answer that, the rest of the management plan falls into place.

He has dozens of these. The pattern is always the same — turn a confusing topic into a single letter or word, and rehearse it until you can recall it without thinking.

How to Use Mark K With Your Other Prep Tools

Mark K is not a stand-alone NCLEX prep program. He is a finishing tool. The students who get the most out of his lectures are the ones who already have a working content foundation from somewhere else — UWorld, NRSNG (now Nurse.com Academy), Saunders, or Kaplan — and use Mark K to consolidate.

The typical high-scoring pattern looks like this. The first two months of study are heavy on practice questions and rationales, usually through UWorld or a similar bank. You build a baseline of how the NCLEX phrases its items and which topics give you trouble. Then, in the last three weeks, you switch modes. You stop drilling new content and start listening to Mark K while you continue doing 75-100 practice questions a day. The lectures become a layer of strategy on top of the knowledge you already have.

This is also where Saunders fits in. Many students use the Saunders Comprehensive Review as a reference book — not something to read cover to cover, but something to flip open when Mark K mentions a topic you feel shaky on. The combination works because they complement each other: Saunders is dense and thorough, Mark K is fast and pattern-based.

NRSNG and the newer Nurse.com Academy add a different layer: visual content. If you are someone who needs to see a diagram of the renin-angiotensin system before the audio explanation lands, pair Mark K with a video course. Listen first, then watch the corresponding visual lesson, then do questions on that topic. The triple-pass approach is more time-intensive but tends to produce the best retention.

What you should not do is try to start Mark K in week one of your study plan. Without a content foundation, the lectures feel like a string of disconnected rules, and the mnemonics do not stick. Save him for the home stretch.

Where Mark K Wins, and Where He Falls Short

No prep resource is perfect, and Mark K has known limitations. His audio is older — most of the recordings reference drug names and protocols from a decade or more ago. The clinical principles remain accurate, but you will occasionally hear him mention a medication that has since been replaced by something newer or had a black-box warning added. None of this is a deal-breaker because the NCLEX itself updates slowly, but it is worth knowing.

His teaching style is also polarizing. He uses humor, occasional sarcasm, and a few jokes that have not aged perfectly. Most students find him charming. A few find him distracting. If the first ten minutes of tape one do not click with you, try tape three (endocrine) instead — the content is so high-yield that even reluctant listeners tend to come around.

Where he genuinely shines is in the categories that confuse everyone. Acid-base, endocrine, SATA strategy, and prioritization are areas where most students arrive at the exam still unsure. Mark K's frameworks are not the only ones that work, but they are the cleanest and the most often referenced by people who passed on the first attempt.

The other major strength is accessibility. Audio learners — students with long commutes, parents studying after kids are in bed, anyone who learns better by ear than by reading — get an enormous advantage from a fully audio course. You can listen while walking, driving, cooking, or folding laundry. Multiply that by three weeks and you have added thirty hours of focused study time you would not have otherwise had.

Why Mark K Works Especially Well for Certain Learners

Two groups in particular tend to get the most out of Mark K: visual learners who already use video courses, and NCLEX re-takers who failed their first attempt.

The visual-learner case is counterintuitive — Mark K is audio-only, after all. But that is exactly why it works. If you have spent weeks watching video lectures and reading textbooks, your visual channel is saturated. Adding audio gives your brain a second pathway to the same material. Many students report that they could not explain acid-base balance after a semester of pathophysiology lectures, then suddenly "got it" after one Mark K tape. The audio frees the visual cortex to focus on practice questions while the lecture plays in the background.

For re-takers, Mark K is almost a default recommendation. A failed NCLEX attempt is rarely a content problem — most failed candidates know the material. It is usually a strategy problem: poor SATA pacing, second-guessing, freezing on priority questions. Those are exactly the areas Mark K is built to fix. If you are studying for a retake, start with tapes 8 (delegation), 11 (SATA), and 12 (wrap-up) before going back to the content tapes. The strategy fixes have higher leverage than re-learning content you already know.

One final note for international graduates and second-language test-takers. Mark K speaks at a moderate pace and uses repetition heavily, which makes his audio more accessible than most native-English NCLEX content. Many internationally educated nurses keep his lectures on repeat for the entire month before their exam date, and the consistent exposure to English-language clinical reasoning vocabulary pays off on test day.

The Bottom Line on Mark K NCLEX Review

Mark K has earned his reputation. He is not flashy, his audio is not new, and he does not pretend to teach the whole nursing curriculum. What he does — better than almost anyone — is teach you how to take the NCLEX. Three weeks of his lectures, paired with a strong question bank and a steady review schedule, is one of the most reliable prep strategies in nursing education.

Use the free YouTube uploads if that is what fits your budget. Buy the official audio if you want clean files and you want to support the instructor. Either way, listen to all twelve tapes, listen to tape eleven twice, and practice the alphabet game on every SATA item you see between now and exam day. The mnemonics will feel silly the first time you use them. They will feel essential by the end of week two.

Combine Mark K with UWorld for questions, Saunders for reference, and a good night's sleep before the exam. That stack has propelled more first-attempt passes than any single product on the market. It is not magic — it is structure, repetition, and a teacher who has done this thousands of times before.

Now stop reading guides and start drilling. Run a final set of mixed-topic questions, listen to tape eight tonight, and trust the process.
