Best course ever

You will love this. I recommend the on Demand courses

Closed Captions for On Demand Courses

The closed captions are incorrect sometimes and does not align when Mark Klimek speaks. This is difficult for those who are hard of hearing and have to rewind to catch the correct word.

I love it! just one concern

I love this review and the set up. I wish the closed captions were 100% correct. It makes it hard to watch without sound. For 400 there shouldn't be any issues with accessibility. Other than that I love the review and the ways he simplified the material to an easier way to remember. I failed my first attempt using another review site, so I can't wait to take the test again and see if I pass. I also wish there was some sort of pre and post assessment to measure progress.

Best course Iout there

Great course. I wish I had this in school. It is the best review of everything.

I enjoyed the course

Very useful resources for all nursing students

I Finally Passed with the help of Klimek Review!

I’ve taken the NCLEX twice before passing. When I was approved to test for the third time I found Dr. Sharon on You Tube in July 2024. I signed up for the Subscription and later decided to take the Review (she would talk about it on the YouTube videos) which was everything (really more) than a person needs to pass the NCLEX. The bottom line is we know the information, but you have to specifically know how to test for the NCLEX and that is what Klimek reviews provides. The most important element to passing is what they teach. The Blue Book is also very helpful and provides a wealth of knowledge. What helped me the most was taking the Klimek Review, listening to it several times….and watching Dr. Sharon break down questions. With those two elements you can definitely pass. I didn’t do the group tutoring because when I thought to do it I was 2 weeks away from testing, but if I didn’t pass that was going to be my next step. But thank God I passed!!!!! I appreciate Klimek so much! They saved my life!

Will pass the NCLEX-RN

Amazing audio visual learning experience. I've taken two live versions without the ability to pause and write important things down. Being able to write the very useful hints, mnemonics and strategies is stellar. Soon to go from a Low Paid Nurse(LPN) to a Real Nurse (RN)! I can, I will, end of story...

Thank you Mark K, Dr Sharron and Trevor.

I took my NCLEX for the second time and I passed! 🙏✨ Mark K’s lectures truly helped me understand the concepts and apply them, especially his prioritization lectures they made such a huge difference. They gave me clarity, confidence, and the ability to think through questions the way NCLEX expects. Combining his lectures with Dr. Sharon’s guidance made everything come together and helped me approach each question with strategy and confidence. These instructors will not let you down their teaching truly reflects what you will see on the NCLEX. The way they break down concepts, priorities, and strategies prepares you to think exactly how the exam expects.

Acid base

I learned a lot and am happy found the review

Lectures Consistent with NCLEX style questions

I found that all the information relayed by Mr. Klimek directly related back to the questions asked and helped with recall when answering.

This review is Amazing!

I love all the stupid ways to remember things. I used that trick during nursing school and I love the way Mark includes those into the lessons.

GET IT RIGHT NOW!!!!

I am taking my NCLEX in less than 2 weeks and I made it a priority to finish this course before focusing on question banks. You learn so much in such a short time, it is unbelievable. The silly things Mark do to make you remember the materials, you will find yourself doing them everyday lol This was worth every penny!

Excellent

Quick and thoughtful information. Thank you very much

Alcoholism

This review has taught me in understanding the core concept of what NCLEX is asking for. We nurses know our core fundamentals but Klimeck Review shows you how to answer the questions. Extremely helpful

Easy Peasy

I struggled with ventilator alarms and settings in nursing school. I'm so glad Mark was able to break it down for me. I was always good with ABGs; however, Mark made it even simpler!!! Grateful.

1st try pass!

I just found out I passed the NGN on the first try in 85 questions, and I literally owe that to Mark! I am someone who actually needed content review before testing, and this course prepared me better than any other way I could have imagined. I literally thought of Mark and his tactics multiple times throughout my exam and can genuinely say I wouldn't have breezed through it without him like I did!

The review of NCLEX is the best on the planet!

All topics are excellent!

Educative and Informative Course

Many things I learned in this course were not explained clearly or mentioned at all in my nursing school. I wish I had known the strategies and principles taught in this course during my nursing program. Anyone preparing for the NCLEX exam MUST watch these videos. The concepts are taught clearly and succinctly. The strategies to remember the facts and concepts are exceptional. It's a MUSt watch for the NCLEX takers!

Acid base imbalance

The test really teach issue. If you get it wrong you do it over and explains why the answer is what it is. It explains it in elementary terms. I had to watch it a few times just to get it but I got it now I learn how to answer all types of acid base questions

Review

I thought it was very helpful and education as it was a big benefit to me. I put large amounts of stress on myself in trying to remember ever detail about different processes, so this course help me be able to understand what details and side effects or symptoms were major to remember. Thank you for doing online studying like such to help out.

My Klimek Review

Like many people who are in a nursing school program we have all heard about the different ways people pass their NCLEX. The level of opportunities are very overwhelming. For me the one consistent direction many nurses I encountered agreed upon was U-World and Mark Klimek. I found some of his stuff online and started to use it but found it to be initially too cumbersome. It wasn't until I met a nurse who told me how to purchase this program online and advised it makes way more sense to actually go through it in person or online. As a graduation gift a friend bought the full program for me and everything that I was told about the program was absolutely correct. For a different way at looking at key nursing principles Klimek does an amazing job at presenting the best way to remember specific information. As you go through each of the classes I was able to take notes and work my way through each lesson relatively with ease and gain something each time. Now that I am in the blue book I am working through all of the lessons trying to commit them to memory and understanding while immersing myself in the blue book. As the blue book does a great job giving concise points for many important disease processes and key nursing information I am using it in tandem with certain online testing programs. My personal way of trying to master the principles is going through each Yellow Book lesson first as a review, finding all of the corelating disease processes in the blue book then creating specific tests around what I just studied in Klimek. Before I started doing this I would blindly just do random tests online and try to study everywhere my deficiencies were based on the testing data and I didn't seem to be making any progress. After this new way using Klimek and the online programs together I have witnessed a dramatic improvement in online scores. As I haven't taken the NCLEX yet I won't know until then how effective my strategy is but I feel as though this process is the most effective way to do this. Pass or fail I will keep using Klimek until I pass my NCLEX and will advise anyone willing to listen that this program really works and should be implemented throughout a person's entire nursing education. I am very grateful to have discovered it. I have since taken and passed the NCLEX and here is my personal path to completing it. First I did only the Klimek program. I watched each class at least twice and then filled out each of the yellow book handouts at least 3 if not more times (laminating a single copy to use an white board marker so you can erase works amazing). I did this until I could relay all of the information back without having to review again. Once I finished watching each course twice I then each night did practice tests on various "Chunks" of information that was in each of the Klimek classes. All you have to do is when you create your test (this works in ATI, Kaplan, U-World, and ATI) just tell the system what topics you want to focus on. I then kept taking these tests using Klimek's theories and passed all of the tests. Now it doesn't cover everything so where Klimek falls short you will have to add to your notes or just review the materials. This whole process took about a month and I worked everyday and every weekend. On my NCLEX there was so much that I didn't know but using the tips and strategies seriously helped me break the questions down and I did the best I could to answer them. My test stopped at 85 questions and I found out soon after that I had passed my test. AGAIN I WILL SAY - If you incorporate what Klimek teaches as you go through nursing school and master it along the way with each test nursing school and the NCLEX won't be as difficult and you will be better equipped to manage it.

On-Demand Course for Next Gen NCLEX

This course was amazing. I only found it a little over a week before I took my RN NCLEX. I finished the whole course and studied like Mark said to. Even though I only had a week to NCLEX i feel like this really helped and it was attainable. I did pass my NCLEX and did it on my first try. Thanks so much for all the info. I will be telling everyone I know that is becoming a nurse to use your course. It is worth it. The only thing I would change is maybe the price, or maybe offering payments. I was lucky enough to be able to afford it, but as a single parent it is hard to come up with that money at one time. Thanks again for everything.

THIS COURSE WAS AMAZING!!

I think this course was truly amazing. I wish I had a professor like Mark Klimek during nursing school, he really nows how to teach material in a easy and efficient way.

acid base balance

On- Demand Course

It was great. However, the translations were way off and there's a part where Mark uses the wrong symbol to indicate less than. I enjoyed the lectures and was happy to have access for 90 days. However, I think for people who ay not pass NCLEX on the first time should be given more time considering the cost of the course. I took my RN and passed after studying for about 11 days. I passed with 85 questions! I liked the psych drugs lecture because I struggled with remembering them in the past. However, I got like 1 question from that topic. The most helpful part of the Course is tips on answering SATA questions and prioritization. I got a lot of questions on that! Thank you!

Acid Base Balance and Ventilators

This course was amazing! ABG interpretations has always been tricky for me but Mark put it in the most simple terms and really made sure we understood. I feel so confident in ABGs and Ventilators.

The Course is excellent, I took my Nclex on the 11-12-2025 and pass at 150 questions after 3 months on-demand course, Thank you so much mark klimek and Dr Sharon

Lab Values

I wish there were more lab values included in this lecture because I have seen other values being tested in practice questions. I like the scoring system however (A-D) which helps, but I wish it was a little better organized too. the spreadsheet/pdf was somewhat all over the place.

i love the simplicity of this lecture

On-Demand Course.Am currently studying with Mark Klimek review on Demand , learning alot here which i was not taught in school. Am positive to be the next RN.

I like the fact that each topic comes with Practice questions to test my knowledge.

I'm upset my school made this more difficult

This was so easy to understand, and Mark is a very engaging lecturer. I wish my nursing professors would've used easy to remember tricks like this when teaching ABGs because I'd probably have a better GPA now.

Lab Values

there was a missed section in the chart for potassium, nothing was discussed about the low = C for assess, prepare, and call even though it is on the chart.

excellent
