I took my test in December 2020 and cleared it on my first try. I used PMP Exam Simulator along with a couple of books on audible. I also had Rita Mulchy but only used the quizzes at the back of the book. My ultimate winner was the PMP Exam Simulator. I did all 1610 questions. I did them in batches of 10, batches of 20, 40, 100 and 5 final length exams. I went back and visited all wrong answers and made notes of why a certain answer was right or wrong. That was my Bible during my revision 3-4 days before the exam. The PMP precast simulator is the ultimate learning tool. I did not touch the PMBOK. The audible books and PM PrepCast was more than enough. I cleared above target in all areas. Good Luck to everyone taking the test!
