"I scheduled the 3 weeks Bootcamp at Heinz Ulm with 7 weeks in advance of my lab date. At first I thaught that was a long time, because I was feeling pretty good with my knowledge. But it turned out I was wrong. I wasn't as prepared as I thaught I was. After the 3 weeks spent with Heinz I knew exactly where I was and what I needed to do. The 7 weeks after the bootcamp were gold for me.
I passed the lab on my first attempt. Thanks Heinz for everything.           CCIE 22805 (Romania)"
