Miss Nancy,
I have followed the FPGEE blueprint and tried to cover all the topics in part A and B. I used CPR, and internet to find required information of all the topics. I feel that CPR is not just enough for the exam, you need to have good basics on all the required topics. I hope u are understanding what I mean.
I read Manan Shroff also, but its material is very less and may not be sufficient. Try to get as much understanding as possible on the listed syllabus.
Passing score is 75, and I think any one can't say how they calculate that.
Its not hard to pass the exam, but there needs to be lot of efforts.
Wishing you all the best.
Regards
Kari
