What Our Students Are Saying
Real feedback from verified students who took the On-Demand NCLEX Review Course.
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 YouTube and signed up for the Subscription — then decided to take the Review course. The bottom line is we know the information, but you have to specifically know how to test for the NCLEX, and that is exactly what Klimek Reviews provides. What helped me most was taking the Review and watching Dr. Sharon break down questions. But thank God I passed! I appreciate Klimek so much — they saved my life!
Wonderful course! Helped me pass the NCLEX-RN!
There are not enough words to describe how helpful this course was. I felt unprepared after three HESI exams, but Mark's way of explaining fundamental concepts and having them "stick" helped me narrow my focus and lessen my testing anxiety. Taking the NCLEX was the best experience I had "during school." If only I had instruction like this during nursing school, I would've felt equipped and confident so much sooner. Thank you very much Mark and Trevor!
On-Demand Course + Live Monthly Tutoring
Extremely grateful I registered for both. The online monthly tutoring with Dr. Sharon and Dr. Pete boosted my confidence — they are excellent: very clear, patient, and encouraging, with a strong focus on test-taking strategies. After finishing the course, I passed the NCLEX. It was absolutely worth the time and money. I graduated BSN 29 years ago and finally decided to take my chance. This course gave me the full gear toward that goal — and it is deeply fulfilling. Thank you.
Refresher Course
Absolutely love Mark K. I attended his live session in Ohio and learned so much. My friends and I would joke about how we would have shed a lot less tears if our professors taught the way Mark does. With my test date coming up, I took the on-demand course as a refresher — extremely helpful. If anyone is worried about the on-demand course not being as informative as the live lectures, the content is the same. I would recommend Mark K to any and everyone studying for NCLEX.
Thank you Mark K, Dr. Sharon 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, which made such a huge difference. They gave me clarity, confidence, and the ability to think through questions the way the NCLEX expects. Combining his lectures with Dr. Sharon's guidance made everything come together. These instructors will not let you down. Their teaching truly reflects what you will see on the exam.
On Demand Course
I want to sincerely thank Mark Klimek for making my nursing journey so much more manageable. His teaching style focuses on understanding core principles, which made the material clear and effective. I recommend going through the content 2-3 times: first watch with the notes, then rewrite without them to reinforce understanding. The number of questions does not define your success. Thank you, Mark Klimek. I will always carry the lessons you taught.
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 memory tricks Mark uses to help you remember the materials? You will find yourself using them every single day. This was worth every penny!
Absolutely Amazing!
I am so glad Mark K finally has on-demand courses available. Worth every single penny! This is exactly what nursing students need to prepare with confidence for the NCLEX.
One of the Most Amazing Courses I Have Ever Done!
I purchased Saturday afternoon and finished by Tuesday evening — not rushing, taking my time and writing everything down. Your course left me wanting more each day. I had to sit through three days of ATI live, and it was horrible. This course is completely different. I will definitely recommend it to others — it is a great asset. Thank you to Mark and to Trevor for putting this together to help nursing students gain a better understanding of concepts.
