So my PMP preparation journey starts from November 2018. I am a busy mom of three with full time Job - no extra time !!
Sources used : PMbok + Simulator only (Simple

)
After going through PMbok once on my own (dedicating 2 hours each night). I purchased the simulator only and give a couple of initial 4 hour tests but never passed in 1st attempt. Looking at my busy schedule I decided to book test date for Feb 28th. I took 6 days off from work + had 2 days of weekend ~ so total 8 days. During that time, I studied day and night. As I want to cover the whole curriculum, So my target was to complete each knowledge area. Therefore starting from the knowledge area where I was weak (getting lowest marks as per simulator), I go through PMbok and then give 50-60 questions test from that knowledge area only.
So I scored above target in all knowledge area tests. Then I decided to give 4 hours tests. I gave four tests and passed all of them. My schedule was to give tests in the morning and look at mistakes + do revision in the evening.
I passed my final exam with three AT and two T's.
I must say this simulator is really good and helpful in preparing for the exam. I used the time and learning module a lot. Also I used the statistics that provide me the opportunity to work on my weaker knowledge areas. Highly recommend this simulator.
