Kaplan is a great resource
I used Kaplan through out nursing school and now that I have graduated, I am using Kaplan to prepare for NCLEX. So far, it has tough questions that make me think. More so, it has videos that I can watch on different topics. Most importantly, at the end of the practice questions, there are rationales to show why I got the answers correct or why I got them wrong. So far, it is a great resource for my NCLEX preparation and I hope that with it, I will pass NCLEX on only one attempt.
