Experience with Eplan Certified exam?

Hello, in about a month I will have my Eplan Certified exam. Right now I'm still busy with following all the training modules, so the exam and course dates are all fairly closely following behind one another. However I am stressing a little bit about the exam. I've heard from my trainer last week that the exam will last a grand total of 1 hour, and you need to answer 50 multiple choice questions. That's a minute and some spare seconds of thinking time per question. Seeing as they market the exam as being 3 days long, my presumption was that we needed to do a little project of some sorts. That's not the case. So I would like to know if anyone in this subreddit has done the exam and what their opinion on it was. Did you succeed? Was it difficult? What do I need to look out for and do I need to practice in my spare time as well? What should I focus on?

Thanks in advance for the answers :)
