Very helpful and nicely explained every topics. I would also suggest some extra lab session required in details.

Shikhar's teaching style is exceptional, one that demonstrates that the trainer has advanced knowledge and lot of confidence on the subject matter of the course. Apart from the above, Shikhar was kind enough to answer my queries despite his busy schedule.This is the first time a trainer in udemy has provided personal support over the internal email. I have taken other courses as well but the trainers never bothered to answer any question raised in Q & A, leave alone provide personal support over email. The third reason is that Shikhar's courses provide lot of knowledge.Unlike other trainers who are struggling themselves and miserly in providing knowledge, his courses leave you fully satisfied in terms of knowledge.I learnt a lot which I couldn't have done with courses of other trainers. I would recommend his courses to other students of Linux who are struggling in their search for excellent trainers.

Niccolò28 November 2019

It is a good course, explained well and clearly in the content. Useful to those who want to take the exam

Chris24 August 2019

This is an excellent course for Linux, certainly one of the most comprehensive on Udemy. Mr. Verma is an excellent teacher also he is responsive to questions in this course and his others. After listening for a few minutes you get used to his accent. If you want to learn redhat/centos 7 you should take this course. You also need to purchase part 1 to get the full instruction for the Rhcsa.

Hillary4 June 2019

It is very informative training. Some concept i need to revisit in order to get them well. Otherwise i a satisfied.

Dhimant8 April 2019

Chris5 October 2018

I was a little scared at first taking any Red Hat Administration courses. But after starting this course, The Instructor quickly calmed my fears He delivered a clearly explanation in each section on all the material Making the Topics easily to be understood, with very explained detailed explanations that puts you at ease. I recommend this course to other students, who want to learn as I did very difficult Topics, that were very easily explained and understood.

Niranjan22 September 2018

The content is great and comprehensive. But the instructor is very repetitive and the flow is constantly disrupted. This makes it hard to follow and transition. When conceptually explaining with examples, instructor needs to be more clear.

Anvesha15 July 2018

My doubts are getting cleared after reading the wonderful lectures. This course module is a complete pack for Red Hat.

Jyoti10 July 2018
