@grad
I will be taking exam IV this month end and will be taking exams 1 & 2 subsequent week(may 3rd) , I am not particularly worried about exams 1& 2 because its not very different from FRM and from the sample questions I felt its easier too .
I will be using PRM handbook as a base reading but while studying for FRM I had earmarked few readings for ex: Hull is good for option pricing etc and Jorion is good for VaR so I will be looking into it also .
are you taking these exams too , let me know your strategy
