To be honest, I am surprised that I got AT on all domains. The reason being, I felt confident in about a mere 20% of my answers, 20% felt like wild guesses and 60% I felt I narrowed down to two possible answers and then guessing from there. What threw me for a loop is the number of questions centred around what the Product Owner do! I am pretty sure the majority of the questions were about the Product Owner and less the Agile Coach/Scrum Master and Agile Team. I definitely did not get that impression using the ACP Exam Simulator on here. Either way, I passed with AT in all domains and I thought I failed. The other surprising thing was no mention of XP programming not even once - just a few mentions of Scrum and Kanban, but most referred to agile in general. I found the exam simulator different in that respect too.
So I followed the same system that allowed me to pass the PMP. It's a quick and dirty approach, but I think if you have a solid project management background in the real world, then this is the quickest way to get there:
1. I didn't do any of the PrepCast Videos. God bless Cornelius, but he talks way too slow and over explains everything. I gave up on the videos a few lectures in. I waited my two weeks and guessed through the quiz to get my certificate.
2. I bought the PMI Agile Practice Guide
3. I just started working through about 30 unanswered questions a day on the ACP Exam Simulator. I failed each quiz for the first few days and for every wrong answer I would read through the explanations and the references if they were in the PMI Agile Practice guide or links online. By the halfway mark, I started averaging over 70% percent on first attempt questions.
4. After the halfway mark I started interspersing practice Exams just to get used to sitting there for long periods of time without blowing my head off in boredom.
5. I scheduled my exam at 10 am, this allowed me to not eat before the exam. I drank black coffee (i.e. no cream or sugar) beforehand for a mental boost. (Research shows students perform better on exams when fasting, but you have to be used to fasting don't make it your first time!)
