Best Online IT Courses for 2021

Filed Under: Resources

I am a huge fan of Udemy platform because it has provided a common platform for instructors and students. The video courses are of high quality and it’s affordable for students across the globe to learn any new technology. You can watch these courses whenever you want and get part in discussions to clear out your confusions.

I have spent last two week to go through Udemy courses and come up with a list of best IT courses, all these are highly rated by students. The price for these courses are nothing when you will apply the knowledge to advance your professional life.

My criteria to list these courses are:

  • Almost 50% of these courses are already taken by me, so I know they are of high quality
  • There are few courses I have selected for 2016, those are also listed here
  • Some of these courses recommendations have come to me from many of our 30,000+ newsletter subscribers
  • Finally, all these courses have thousands of students and have very high rating. The instructors are experienced in their area. They are active in discussions to help students.

I have tried to categorise them but that’s just for quick access. I will keep updating this list as and when I will find new courses that I think should be listed here.
