Used Saunders and Exam Cram didn't pass, Kaplan Strategies Book didn't pass, & now UWORLD is my 3rd option. I finished all of the 1149 questions, read the rationales. Took the 1st predictor test, scored 45%, and it said I have a high chance of passing. I wrote down some notes in the beginning, but then it got very tiring so I just studied them on my phone. I am going to take the 2nd predictor test a week or 2 before my PN test and see where I am at. What do you guys think? I hope I pass this 3rd attempt!
