Please note that I had taken a break to gain this certifiation and had all the time I needed and I could also study at my pace undisturbed. The whole time that I had devoted could run up close to 250 hours. If you are working and still planning to take the exams you are forewarned to plan for the final exam more prudently.
The flip side is, if you fall prey to Parkinson's law and repeatedly postpone the exam, the chances of you ever getting certified also decrease accordingly. 60 to 90 days after the 21 hours Agile coaching is a good target to achieve with razor sharp focus.
Feel free to throw your questions so I can make my experience of ACP exam taking more useful to you. All the Best!!
