I did UWorld 6wks before my exams, as I did RN and PN.
My scores ranges from 44-57%.
Self-assessment 1: 55% - Chance of passing: HIGH
Self-assessment 2: 51% - Chance of passing: BORDER LINE
Took my RN then PN exam, 5 days apart. Stopped at 75 and 85. I passed both.
I know you can do it too! Goodluck!
