Testimonial from other students:

Hi Imran, I have completed this course twice. It was more than just wonderful. It proved to be life changer for me, I had zero knowledge about Linux and now i am working as Linux SysAdmin as i have acquired my dream job.
Thank you so much for the wonderful course. I am looking forward to see some more exciting courses from you.

Regards, -- Hasan Raza

To all of you that are looking for a REALLY GOOD LINUX course, THIS IS IT, SERIOUSLY I promise you won't find a course on LINUX here that is THIS GOOD. -- T.J. Marstiller

Hi Imran, I am so glad to inform you that i got two offers as a Linux engineer. Through your course I gained lot of confidence and your interview tips really helped me a lot to crack the technical rounds. I have recommended your courses to my friends as well. Thank you so much for your efforts in sharing your knowledge to learners like us. -- Subhasree

Hi Sir Imran,

Greetings to you. I am writing this email to give good feedback regarding your course materials that I have watched from Udemy. I have completed your Linux course and I would like to mention that it has been nothing but awesome. Your course has allowed me to obtain a Linux certification and I would like to give a big thanks you for that. Please continue what you're doing and I wish you the very best. -- Yusuf Ishkandersha

Imran is a very knowledgeable and engaging instructor. As others have said, you can tell that he is not just trying to sell a course, but that he is invested in giving his students a strong career foundation with a positive and approachable attitude. He is also entertaining with his use of pop culture and practical work examples. It really feels like you're in a classroom with him. I'm taking this course mainly as a hobbyist, but got a lot from it already. The homework assignments, quizzes, and handouts help reinforce the material. -- Raymond B.

I just love the teaching ad the learning experience I am getting -- Jacob Samba (Udemy Student)

Imran Afzal might be my favorite teacher I've EVER had. He is funny, and engaging. The course was easy to follow, and with no experience starting I am now extremely comfortable with Linux, and actually really like it. He does make you do your googles, but this is not a bad thing especially considering the nature of IT and documentation to solve your own problems. I highly recommend. -- Vanessa Diaz-Goumond (Udemy Student)

The course is run very well and I really like the handouts and the homework that is assigned. The homework helps me learn and continue with the learning process even when adult life is still progressing forward. -- Thomas Rogers (Udemy Student)

Such an amazing instructor. Imran must have put in a lot of effort in structuring the course and taking the student step by step, he takes his time in explaining everything, from what Linux is, how to down load it, coding, etc. I have taken other courses from Imran. I am a student for life. Keep it up and please keep preparing more courses for please like us who can benefit from your way of teaching, knowledge and experience. Thank you. -- Ali Shiekh (Udemy Student)

In the first place I say a big thank you to the instructor for making such a great course. I was afraid to learn Linux. I now feel very comfortable with Linux. I have understood both the concept behind and the practical as well. I would recommend every one who is NEW to Linux and wants to grab it once and for all without wasting time to go ahead and ENROLL. You will not regret it. I would like the instructor to do same for WINDOWS SERVER ADMIN., I don't seem to find any better and beginner oriented course out there that could be matched with this course. To me, it is the BEST Linux Course on Online. I just started some real world projects with Linux after this great course, I was new to Linux and in just a month I am on the command line always playing. -- Opoku Bright (Udemy Student)

I genuinely look forward to additional courses in the future. This has been so informative. You hear the name oracle all the time, but this was well put in layman’s terms -- Atoofa Hasan (Classroom Student)

Imran Afzal eats, breathes and sleeps Linux! He really knows his stuff. I feel like he has brought me from a novice level education to masters level in a short time period. Anyone who is looking to get a job in Linux should definitely take this course. -- TJ Walker (Udemy Student)
