Easy to study and understand
Format: Paperback
This book is easy to read and i tend to recall information better after reading it. It breaks down topics and focused on the important information or a must to know for NCLEX. I will recommend this book to anyone taking NCLEX.

Great book!
Format: Paperback, Format: Paperback
I am still in nursing school- but I like to try read and gain knowledge ahead of time. I do this so that with upcoming semesters, the concepts are not completely foreign to me and I’m not blindsided by new topics. I have been following a lot of the YouTube videos with Mark and Dr. Sharon and have found them very educational even while in nursing school. I purchased this book and I really am happy with it. I was hoping it would have offer more info in it , maybe some more facts here and there but it’s basically an answer bank. It does have some small facts but they are not in depth at all- just mainly recall information. It really is based off just past memory from your education. For me personally, I find this book pretty useful to have if you feel confident in all topics- and plan to go for your NCLEX..however, if you’re still a bit rusty on some topics, you won’t really be able to rely solely on this book to brush up on information- not in a manner of depth (which I guess is the point). I think applying his lectures, listening to their YouTube videos and applying this book would make the ultimate go-to. The book alone is wonderful- but it’s simply just answer banks to help recall the info. Which is great if you’re looking for strictly recall. I was fortunate enough to find his lectures on Reddit along with some of the “yellow pages” from other students. I can apply that with this book and be confident in upcoming tests , as his lectures are incredible.
