Well, I was a bit stressed about this certification. I have not worked that much in Sitecore lately and I did not really prepared for this exam. I participated at Sitecore MVP Summit 2018 and up until the evening before the day the exam was scheduled I was not 100% that I really want to take the exam, but made my mind and in the morning at 8:00 I was present in the room to take the exam, even that I was bit tired.
After signing up at the location – took a bit to do it – the exam started. There were 50 questions, with a countdown of 1h and 30 minutes, but apparently the room was booked for something else at 09:00, so I had a bit more than 1 minute for each question. That went quite well and I’ve passed the exam and now I am a Sitecore® 9.0 Certified Platform Associate Developer.
