I passed my PMI-ACP exam with Above Target in all Domains.
I used the AgilePrepCast Premium subscription as my main source of preparation, and can reassure you that it money well spent.
First, you need to prepare for the exam. It is nothing like a walk in the park.
Second, take note of the reference material given in the videos and at the end of the simulator exams. Most of them are articles that take about 5 minutes of reading to chunk relevant material.
Third, subscribe for the simulator exams and read through answers carefully, especially the ones you get correct because there is a likelihood of your brain creating an ILLUSION OF COMPETENCE.
Last, use the Pomodoro Technique on video. It is great to know that the podcast feature provides concise tutorials that fit well into the timeframe required for a Pomodoro.
Utilize it!
Interleaving is a learning strategy I used to enhance long-term retention of study content. Try it out!
