Hi , I passed PMP exam on 2nd try on 9^th July. Here is my learnings 

After I failed first time ,I changed the strategy instead of KA – I followed by process groups. That gave me a better overall picture

I sticked to PMBOK and PMP Training Kit by Sean Whitaker which is a good book.

OSP PMP is good and Corneiuis strikes at basic stuff.I scored 80%(attempted 3) in  200 Q EXAMS

Fahad of PMStudy circle also does the same.I scores 75% and 78 IN 2 tests

Oliver – 175q -59%

Oliver -75q – 64%
