Hi David,

Not too bad - got 935/1000 with pass mark 804.

Will crack on with the ICND2 now so will be back in touch next week maybe depending on how it goes.

Cheers!

Thank You

Great TOOL!!!! (CCIE Command Memorizer)

Robert Pethick

 

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.

At first glance, this is as awesome as I hoped from the website.

Really glad I stumbled across it!

My CCNA just expired and I wasn't quite ready to go for the BSCI, so I need something to review.  And the look and feel of your material is STUNNING.

thanks again,
