I started my prep in mid-July right after I booked my exam date for end of September. I started out with Joseph Phillips PMP exam prep course on Udemy and would read the Rita simultaneously after each section. After doing a few free practice tests online, I decided to buy the PMP Exam Simulator access and attempted to do one a week. That didn't work out...Did the last two the day before the exam, averaged in the 70s bracket...did some of the quizzes as well. Tried to make the effort to review the ones I got incorrect especially. Was able to pass on my first attempt. The PMP Exam Simulator is certainly value for money.
