Hi David,

Once again thanks so much for knocking together such a great study aid! In my opinion, its one thing knowing the material well, and a completely different one understanding what is required of you on the day of the test – your software and simulations, without a doubt in my mind, gave me the edge I needed on the day of the test.

Really hoping that you are going to extend this kind of offering to the CCDA, CCDP and CCNP.

Kind regards,

This is my first newsletter, I came across your IOS tips ebook searching through google, and didn't mind getting the newsletter. Now, I'd like to say wow!

Its awesome, I'm really glad I signed up--kron jobs on IOS? I didn't know you could do that! The information is incredibly well presented.

When I can tear myself away from study, I'll update my blog, and give your site a plug, you provide some fantastic resources that you don't really see anywhere else, thanks!

Greets!

I think the new version of the command memorizer is brilliant and has been a massive help during studying for the exams

Thanks for the quick response. Feel free to use the comments. If you’d like to add something else I will tell you that I found your proof-readers to be particularly good.

This is my 8th certification test in the last year and frequently the answers that are given are just blantantly wrong.

It was a good feeling to not find myself confused.

Hi David,

Success!!! I passed - 83% :-)  Thanks for the course this week, it's been excellent. I've been buzzing every night when I got home, my Wife thinks I'm turning into an anorak!!! Your presentation of the course was, in my opinion, superb - I
found the way it was snappy & fast paced kept me switched on to the subject all the time, even though I was completely flaked out at the end of each evening!

Thanks again - if I ever get the opportunity to recommend your training services within BT then I will do so without hesitation.

Regards,
Neil.

David,

Thanks! It went very well,

I passed the test. Yehaw!

I attribute my success to the time spent using the CCNA Knowledge Verifier testing application.

It covered important concepts and operational tasks that were covered on the CCNA test.

The Command Line Memorizer section provided additional insight into many of the troubleshooting exercises.

Thanks again for your help.
