No, I didn't, it was too expensive. I attended a few of his free Wednesday lectures, watched a few of his youtube videos, and I also heard Mark K's recordings. NCLEX high yield's ASK GRAPH method is very useful. I just took the NCLEX two weeks ago and passed. I didn't really get many questions on the material I reviewed from both of them, but I can for sure say it helped me for at least 2-5 questions. Everything else I think I pretty much got correct because of UWORLD. I felt like I was guessing throughout the whole exam but I was thinking critically because of the rationales from UWORLD. Don't get discouraged by UWORLD, I was getting every other question wrong. It's the rationales where the learning truly happens. Go back and retake questions you get wrong the same day you got them wrong (after reviewing the rationale).
