    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 !!

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

  12. 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?

    1. 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.

  13. Ptlhanang

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

    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!

    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

    Just passed Sec+ today thanks mostly to these videos. It’s been 6 years since I took IS-security courses so this was the perfect refresher.

    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.
