Here are my students’ comments:

• To anyone looking for a really good course on Linux, here it is. I seriously promise you won’t find a course on Linux this good here. — TJ Marstiller (Udemy student)

• Omran is a very knowledgeable and engaging trainer. As others have said, you can tell he’s not just interested in selling a course, but is invested in giving his students a good professional foundation with a positive, approachable attitude. He also enjoys using pop culture and real-world work examples. You really feel like you’re in the classroom with him. I’m taking the course mostly as a hobby, but I’ve gotten a lot out of it. Homework, quizzes, and booklets help reinforce the content. — Raymond B. (Udemy student)

• The most important thing about the course is its simplicity and hierarchy. The design is very good and simple and helps you understand the problems better. — Akash Garg (Udemy Student)

• I just love the teaching display, the learning experience that I have – Jacob Samba (Udemy Student)

• Imran Afzal is perhaps my favorite teacher I’ve ever had. He’s funny and charming. The course was easy to follow and considering I had no experience when I started, I’m now very familiar with Linux and I really like it. He makes you 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 is going very well and I really like the booklets and homework that is delegated. Homework helps me to learn and continue the learning process even when adult life is still going on. — Thomas Rogers (Udemy student)

• Such a great teacher. Omran must have put a lot of effort in structuring the lesson and explaining to the students step by step what it means to explain everything from Linux to loading to coding and… It takes time. I have other lessons from Imran. I am a lifelong student. Keep up the same and please prepare more courses for us who can benefit from your teaching method, knowledge and experience. Thank you very much. — Ali Sheikh (Udemi student)

• Thanks to the instructor for even making such a great course. I was scared I would learn Linux. I am comfortable with Linux now. I have understood both the concept behind it and the application. I would recommend it to all Linux newbies who want to use it and sign up once and for all without wasting time. You won’t regret it. I WOULD LOVE THE INSTRUCTOR TO DO THE SAME FOR WINDOWS SERVER ADMINISTRATOR. “I don’t seem to find a better beginner-oriented course out there that can compete with this course.” For me, this is the best Linux online course. After this great course, I recently started a few real-world projects with Linux. “I just started with Linux and within a month I am always on the command line and always playing.” — Opoku Bright (Udemy student)

• I am very excited to take more courses in the future. This was very educational. You will always hear the name Oracle, but it is well expressed in slang –

• Omran Afzal eats, breathes and sleeps Linux! He really knows his stuff. I feel like it took me from a beginner level to a master level in a short period of time. Anyone who wants to work on Linux must have completed this course. — TJ Walker (Udemy student)
