    Professor Messer -

    THANK YOU for making these training videos available – I’ve been able to get my A+ and Network+ certs, and am preparing for the Security+ test. Excellent videos – very clear, understandable and to the point with many current and valuable website references. I spent 3 months of self-study for the A+ and got very high scores, then 13 months on Network+ and got 840 out of 900 – thanks to the Professor Messer video series. I just finished viewing all the Security+ videos you produced, and I compliment you on a fabulous job. You really know your stuff !!

      The SY0-301 was released at the end of May, but you can still take the SY0-201 until December 31st of 2011.

      • Mike

        Thanks Prof Messer..that is good news indeed.u00a0 Just passed my Net+ with an 867 with a lot of time on Exam collection and your youtube vids…Thanks for your help!

  • Saadzaki

    I’m goging to do the Network+ exam, the next step is Security+. Thank you Professor, you are the best in field.

  • Professor Messer

    No short-term plans for a PCI DSS training course, but it’s a great idea!

  • Michelle

    Since these are SY0-301, how well will this prepare someone for the SY0-201 exam?u00a0 Will this throw me off course or cover a good amount?

    • Professor Messer

      Michelle, the SY0-201 has many similar topics, but there is a lot of new content on the SY0-301 that you won’t see on the SY0-201. Make sure you refer to CompTIA’s exam requirements documents for both exams to compare the differences.

  • Ptlhanang

    all the videos are awesome and most of all they are free and very easy to understand. Thanks Professor Messer, You Rock!

  • Joe M

    Thank you for the amazing videos! I found your site about a week before my Security+ exam and watched as many as I could and passed the exam. If I had known about your site earlier, I would have purchased your training material, BOTH because of the quality of the videos, and to support the service you are providing. I sincerely hope you continue to add new subjects. My votes go to more CompTIA exams (e.g. Linux+, Project+), and more security oriented exams (CISSP). Thanks again!

  • Tommyg112

    Professor Messer this training is awesome. Thanks for helping me pass my exam yesterday. I did study the book and had taken practice test before finding your link a few days before my exam. Then I watched the entire training modules and it helped me understand some of the topics I was weak in. Great Job and Thanks

  • Ronnie Byers

    I passed SY-101 in 2008, a new job requirement required me to pass SY-301. I found these videos while googling for study material – I grinded through them over the course of about 2 days, and not only did I pass with flying colors, I now have a much better understanding of information security as an IT professional. Professor Messer, you are an invaluable resource to the community. Thank you! I will be purchasing your books for my future certifications.
