For myself, it took about 7 months. That includes:
-Listened to all the Prepcast lessons (twice)
-Read the PMBOK (twice)
-Read the Rita book
-All the Prepcast Simulator exams (+ time for going through the answers)
-4 other mock exams (full length)
-Misc time for Youtube videos, articles, agile book, etc
I could've done it in less time but I decided to take it to my own pace. Passed with 4AT + 1T
