I passed NCLEX-RN after 2.5 months studying of UWorld. Without doubt UWorld is the best study material for passing NCLEX-RN. I studied hard from morning till noon with 80 tests every day.I did 5 self assessments and I got very hight exam result. In the exam my monitor was blanked at 86. I had 4-5 exactly similar questions word by word like as uworld questions. The platform and the concept of questions were like UWorld. If you read rationals you will be able to answers most of the questions 10000%. In one sentence UWorld is best of best. Thank you
