    More please! Your free training aids were invaluable in my A+ essentials and technician studies. With your help, I have my 601 and 602 certification. I am now studying for my Network+ certification.

    A great, well presented and well delivered video series – I’ve watched the lot!

    Together with seemingly endless knowledge, your uncanny ability to mind-read has amused and enlightened me throughout and I’m very grateful to you.

    Many thanks for your help on my looming 601 and 602 exams.

    I’m currently studying A+ and Network+. This is a great companion, and helps fill in the gaps of stuff that I may not quite get. Your video on OSI layer REALLY helped me ‘get it’.
