I finally pass PDD, on my 3rd try.
I did not do anything different this time, I guess the more you study the more prepare you get.
My main study material was Black spectacle, but I also used Ballast book and Exams, Hyper Fine Architecture Exams, Designer Hack Exams, Amber Exams.
Also, every time I took the exam, I looked for more information on the questions I was not sure about, and thank god I did, because I got a couple of questions from my previews fail exam.
Good luck everyone.
