After receiving my ABIM board results today I must say you guys haven't failed. This is way better than MKSAP. Your questions were so similar to the board exams questions and interface was amazing.

UWorld's NCLEX™ Test Prep offers more rationales and diagrams for each answer along with an objective to the question. This is more than any other Test Prep I have used in the past such as ATI, HESI, and LWW.
