Here is the testimonial from my students:

  • 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 (Udemy Student)


  • 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.  (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.

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.
