I'm now ACP since 31st January. Let me tell you about my studying...
Started preparing for the exam last year in April. Bought a prep book and in addition I participated in a prep course 1h/week for 8 weeks organized by my employer. Due to vacations and a lot of work I put the whole thing on hold from July to December. As this was WIP it started to bother me. I'm commuting almost daily several hours and my inspiring manager suggested that I'll try to listen to either some nice books or some learning during this time. That was in beginning of December when I found Cornelius - my new friend! The prep cast inspired me to start over and go for the exam.
The exam itself tested the mindset more than any facts or figures. I also did a brain dump but don't think it was of any benefit as the questions were almost all situational. Compared to the PMP exam this was for me much harder as you could not rely on some facts that you had memorized but needed to really think of the situation described and try to find the best option based on that.
Good Luck to all of you studying for ACP!
