Divya Harave, CCIE #19721
I used a workbook from INE for my CCIE R&S lab in 2007 December. A friend had shared the material (he was also preparing) and this really helped a lot, purely to practice timing. I used to do half labs at one shot, with routers blocked for 4 hours each every evening. I did this for three weeks and after that passing the exam seemed easy. It was my third attempt so I had to get it right this time but after I gave the lab exam (with 1 hour to spare!!) I wondered why I didn't do this preparation at the first attempt, I could have passed so well ;) Thanks INE!
