G.P. Boarina, CCIE #38619
I've been in the London bootcamp in August 2012 with Brian Dennis and passed CCIE R&S exam in March 2013. The greatest lesson that Brian has taught me in the bootcamp was how to spot a problem *before* it happens instead of just troubleshooting it later. This was the key to succeed in the lab. I recommed to join INE bootcamp when you're in the final preparation of the exam (about 3 months) because it gives the final boost to enter the lab with confidence and very good chances to pass.
