"Hi Everyone, I took my TCP/IP today with score of 948/1000, your exam preparation is excellent and good value for money. What I like about your test is the layout, dividing test into different topics, that way it is easy to spot your weak areas. I would recommend anyone out there to check your Test Prep before taking any Microsoft Exams." —Abdi Elmi


"I had just appeared for the TCP/IP exam, and it was quite tough. Your questions proved to be very useful additional source besides my Sybex guide. My score, 879, though I expected in 900s."  —Steven Chiu, Calcutta, India


“Passed the Microsoft TCP/IP in the mid-nineties! Glad I had your tool.” —Robert Vettor, U.S.A.


"...As for TCP/IP,  I made 965 which means I missed 2 out of 58. I was positive  that two of the questions had no correct answers... As for your tutorial, it is the ‘bomb’. I don't know if you know that term means where you live, but my 15 year old daughter uses it to refer to something that is excellent. I was totally prepared and did not see anything that the tutorial did not cover in detail. Keep up the good work!" —Jim Newton, U.S.A.


“Thanks for your tutorial. You helped me pass TCP/IP and other MS Exams. Just wanted to say thanks, big time!! Thank you for your assistance in this matter." —John Devereaux, HP Computers
