" WOW - I thought – I really passed it ! What a wonderful feeling after the endless hours of studying before the exam. I cannot explain how good this feels. But those of you who have done the exam will know what I mean. I think I would not have passed it on the 1st attempt without the weeks of full-time preparation right before the exam. Special thanks to Heinz Ulm (aka Drill-Heinz) and Heiko Groeger, instructors at the famous Heinz Ulm Bootcamp for the challenging mock labs, and all the good advice. MOCK H was EVIL !! "
