Here are my students’ comments:

• To all of you looking for a really good course for Linux, this is it، i seriously promise you won’t find a course on Linux that’s as good here. — T.J. Marstiller (Udemy Student)

• Omran is a very knowledgeable and attractive coach. As others have said, you can say he’s not just trying to sell a course, but investing in making his students have strong job foundations with a positive, accessible attitude. He’s also fun using pop culture and practical work examples. You really feel like you’re in the classroom with him. I take the course mainly as a hobby, but I’ve already taken a lot from it. Homework, tests, and leaflets help reinforce the content. — Raymond B. (student Udemy)

• The main thing about the course is its simplicity and hierarchy. The design is very good and easy to help you better understand the issues. — Akash Garg ( Udemy Student)

• I just love the teaching ad, the learning experience I have – Jacob Samba (Udemy student)

• Imran Afzal may be my favorite teacher I have ever had. He is funny and charming. It was easy to follow the course, and without any experience at the start, I am now very comfortable with Linux and I really like it. He’s getting you to do his Google, but that’s not a bad thing especially given the nature of IT and documentation to solve his problems. I highly recommend. — Vanessa Diaz-Gumund (Udemy student)

• The course runs very well and I like the pamphlets and homework that is delegated very much. Homework helps me to learn and continue the learning process, even when adult life is still in progress. — Thomas Rogers (Udemy student)

• Such an amazing instructor. Omran must have put a lot of effort into structuring the lesson and step by step student, what’s in explaining everything from Linux, how to load it, coding and … It takes time. I have other lessons from Imran. I am a lifelong student. Go on the same and please prepare more courses for us that can benefit from your teaching method, knowledge and experience. Thank you. — Ali Sheikh (Udemi student)

• Thank the lecturer for making such a great course in the first place. I was afraid I would learn Linux. I feel comfortable with Linux now. I have understood both the concept behind and the application. I would recommend to all those newcomers to Linux who want to use it and sign up once and for all without wasting time. You will not regret it. I WOULD LOVE THE TEACHER TO DO THE SAME FOR WINDOWS SERVER ADMIN، I don’t seem to find any better, beginner-oriented course there that can match that course. For me, this is the best Linux online course. I recently started a few real-world projects with Linux after this great course، I just got into Linux and I’m always on the command line within a month and I always play. — Opoku Bright (Udemy student)

• I’m really keen on additional courses in the future. That has been very educational. You’ll always hear the name Oracle, but it’s well-expressed in slang —

• Omran Afzal eats Linux, breathes and sleeps! He really knows his stuff. I feel it has taken me from a beginner’s education level to a master’s level in a short time. Anyone looking to work in Linux must have completed this course. — TJ Walker (Udemy student)
