My story basically consist of 6 month of practice and 6 month working with Workbook 2. I took ALL MOCK labs and felt pretty confident before my first (failed) attempt. However , Internetwork Expert stuff , especially Mike and Petr Lapukhov help me to concentrate and finally pass my second attempt after 30 days. Petr looked at my particular situation and give me advice , which finally made vital point in my success. I am still under impression of his level of expertise and I really value his advice.
