I passed my CCIE on the 28th of April 2011 on my first attempt. The Workbook Vol I from INE helped me a lot to dive deep into the technologies that are required in the R&S exam.
But what helped me the most was having an excellent and motivated study partner. Together we were a study team that never gave up. Special thanks to you, Mirko :)
