Here's what satisfied customers have to say about the value of the subscriptions to Certification Zone.com:

"...in August I became CCIE #7945. The Study Guides on [Certification Zone] were extremely helpful in making this possible. I found the Study Guides on Frame Relay and ISDN [by David Wolsefer] especially useful. After failing the CCIE Lab twice, I purchased a Subscription to the Certification Zone and passed on my third attempt, just one month later. Thanks!"

"I have passed the CCIE Written Qualification Exam on January 19, 2002. I have been preparing for it for the last seven months and used a lot of Cisco press books [including], CCIE LAN Switching, Routing TCP/IP I & II, the CCIE Routing & Switching Exam Cram book from H. Benjamin, and the CCIE Routing and Switching Exam Guide 350-001 from Lucent NetCare. But, I found it extremely difficult to put all the relevant topics together and concentrate on the exam objectives."

After receiving an email from Certification Zone, I decided to subscribe to Certification Zone for three months. From that point onward, I used only Certification Zone Study Guides and the Study Questions. I [also] attempted Certification Zone's Practice Exam frequently.

On the last day of my 3-month subscription, I decided to try the Exam. [Up] until then I had done all the 12 Practice Exams and passed 5 of them with the highest mark of 825. My plans were if I failed the first attempt, [then] I will study for another 2 months before my 2nd attempt. I passed the exam with 81% score, which I feel, [is] a very good one.

I [would like to] take this opportunity to thank Certification Zone web masters on their excellent effort for showing the correct path for passing the exam successfully. Especially the 2 ATM papers, Bridging, Token Ring papers are excellent without taking anything away from other papers which are also very comprehensive and very good.

Excerpt from 12/01 issue of Certification Magazine, written by professional IT Trainer Ed Tittel:

"Certification Zone: Covers only Cisco certifications, but is nearly my ideal of a model site: It offers great student support, lots of reasonably priced supporting materials and publications, access to big-name experts, tie-ins for online training programs and lots of support for students. Subscriptions cost between $15 and $23 a month, depending on the subscription period you elect to pay for, but it does provide access to lots of useful information, including study guides, practice tests and discussion groups galore."

I think Certification Zone is one of the best sites of its kind with the most qualified authors/contributors. I use the Study Guides daily in my job.

Jeff Soucy, CCNP, CCNA

The (ZONE's) tutorials are absolutely the BEST self-study materials I have seen. They somehow manage to condense key concepts into a few pages of excellently written material that is easy to understand. You definitely have some of the best the industry has to offer writing for you. I also used the practice exams which I thought were tougher than the real exam. I feel that is the way it should be.

I love (your site). I have multiple certifications, and (Certification Zone) is the best study site I have ever used. The mix of tutorials, study questions, and hands-on labs is in my opinion the best way to learn any subject. I have recommended (Certification Zone) to many friends, and I have recommended (Certification Zone) to my employer as a self-study site for new engineers. Keep up the good work!

(Certification Zone is the) best certification site I have found for Cisco, and I'm pretty sure I've seen them all. Other than the occasional typo and missing graphic, the practice tests are second to none.

Ray Brehm, CCNP, CCNA

The material (at Certification Zone) is presented in a very professional and concise manner. The contributors of the material seem to be very knowledgeable and go the extra distance to explain concepts and fundamentals. This was very helpful to me because if I get hung up on a particular topic, it is extremely difficult to build off it. Kudos to the creators of the site and the staff which operates it. I would recommend this technical site to anyone who was serious about becoming Cisco certified as well as a great technical reference site.

Steve Gitto, CCNA

You're study materials have helped my understanding of networking topics tremendously. I work for a major ISP and deal with WAN issues 99.999% of the time, the study guides for the lan switching test has helped with my prep work for the Cisco Lan switching test.

J.M. Manning, CCNA

I have used Certification Zone as one of my primary certification study tools and I like it for the quality of content in the study guides as well as for the practice tests. The practice tests are the best I have used and I have them all.

"The money [you pay for a subscription to Certification Zone.com] is worth it. The Study Guides, labs & exams are top-notch, I haven't seen its equal. You [usually] get [free access] to a tutorial each month, so you can check them out ahead of time, but the archives are what's worth the money."

Robert Timmons CCNP, CCDP

"I think one of the big things that made the difference was the subscription to Certification Zone... I must admit the questions in my exam were more on par with the level of the questions on Cert Zone and the (new Certification Zone.com) Study Questions CDROM."

Nigel Taylor

"This morning I passed [the CCIE written exam] with a 75%... The practice tests and white papers (at Certification Zone.com) are great. Well worth the money."

Chuck Church

"I'm writing this to tell you how much I appreciated the Certification Zone web site. I felt that the [STUDY GUIDES] were very well thought out, informative, and well written... They helped me fill in some blanks that the (Cisco Networking Academy) curriculum left sketchy. [Your site's] simulated practice exams were an excellent tool to judge my progress and to identify my weak areas. The explanations given after each question were very helpful.

....With the knowledge and confidence that I received from this site, (and a lot of studying), I earned a score of 914/1000 on the CCNA exam.

Sincerely,
Michael P. Donnelly, CCNA"

I am now seeking the CCNP™. Next week I take the CLSC™ and the ACRC™. Your website is the reason for my confidence in even considering the task. I thank you for the help... and keep up the outstanding job."

Daniel A Calix, CCNA

"I just passed the CCIE™ written exam and wanted to let you know that Certification Zone's Practice Tests are excellent!!! I used them to help me prepare for the exam and I can attest to the fact that the Zone's practice tests are a good gauge for the real test. I got a 74.8 score on your practice test and an 82% on the actual exam. The explanations you provide on the scoring summary were really good, also. Just keep it coming."

Larry Dwyer

"I thought the CertificationZone tests were slightly harder than the real thing. They helped me tremendously to prepare for the actual exam. I passed the CCIE™ R/S Qualification test with an 86. Thanks to all the fine folks at CertificationZone."

William Hansen

"My Cisco®© classes used your CCNA™ Study Zone last semester. My students were very impressed with the resources available, especially the SIMULATED EXAMS! We found them to be a great prep tool for the CCNA™ Certification exam... the White Papers are great resources along with the sample questions that accompany each topic. We look forward to using the site again this spring."

Bruce Roehrkasse

"The Zone helps quite a bit explaining the workings of the test. I know how to do a lot of the stuff required, but the Zone helps me understand why it needs doing."

Terry Johnson

"I used Certification Zone to prep for the CCIE™ written. It was AWSOME. Kudos Howard!!! I started taking the Zone's simulated exam about 4 months before taking the real thing. Boy did they kick my butt. I think I got a 36%. I got an understanding of the structure of the questions and the slant that the questions would take. Reviewing the correct answers helped tremendously. After the 4 month period I finally scored an 87%. Two days later I got an 85% on the real exam. That tells me that Howard has done a great job setting the level of the exam extremely close to the real thing."

Joe Martin

I still use it to refresh my memory."

Liz Howell, CCNA
