FOLLOW PROFESSOR MESSER:

[Sammy-rscd]

Professor Messer is really a boss at teaching. He's able to completly catch my attention and makes me really concentrated while watching his explanation

[kevinurielfonseca]

I just passed my 220-901 one hour ago and I'm just here to say "Thank Professor Messer", all of the videos are just great for studying and I love that I did not have no read/watch extra stuff as when I was in the technical school.

I got my A+ back in 2001 (in Tallahassee!) and was hoping to update my knowledge. Particularly WiFi, mobile, and HDMI/DVI. This playlist was perfect for that! I filled in those gaps and got lots more great info. Thanks so much, Professor for helping an old techie feel young again. :)

I just wanted to say thank you Professor Messer! You are such a huge part of me passing my 220-901 last weekend! I bought your study guides for both and they really helped me. I will be taking the 220-902 next week and I'm confident that I'll pass that one as well with your videos and documentation. Again, thank you!!

[MZSabrinaRJ]

Your course videos are very Informative and are a great study aid! I like that you stick to the important points and don't add unnecessary information. I greatly appreciate this series!

I just wanted to say thank you Professor Messer! You are such a huge part of me passing my 220-901 yesterday. I am preparing for my 902 in a few weeks times. God bless you

I have just purchased physical copy of the A+ training by Professor Messer after watching these video tutorial. I have every reason to grab my copy because Professor Messer is extremely good and breakdown the training to an extent that one could still understand every bit of the tutorial even without basic computer background. Nice job prof.

[hassanlotfi]

One of the best options for this tutorial is to provide understandable subtitles. Thank you very much, dear professor

[aydrianna]

Your videos helped me immensely. I crammed for 2 nights before the exam which I DO NOT RECOMMEND but your videos are the only reason I passed both the 901 and 902. Now I'm getting ready for the Network + (which I have way more time for) and I know you will again be a great source of help. Thank you!

[PhilpotWildman]

Just passed my 901 exam, thank you very much professor, you are doing great job!

[darkninjaoflightness]

Thank you Professor! I passed the 901 today easily! I studied from a lot of sources, including these videos and an actual class, but I really recommend people get Prof. Messer's Q&A book. The massive amount of practice questions helped a lot.

[collinsc]

Thanks to your free course videos and practice tests i just passed my 901 exam with 765 today! I look forward to tackle 902 now and i'm confident i'll knock it out too! Keep up the good work Prof. You are helping alot of us:)

These videos are a big help. I also did every free practice question I could find online. Wrote down everything I didn't know and looked it up. I scored over 800 on the 901. I will be done with the 902 in a week.
