Why You Should Take These Courses ?

You can learn the entire Bachelor’s Curriculum of Operating Systems Subject which is taught in Engineering Colleges

  • Without leaving the comfort of your home 
  • Without any prerequisite in Computer Science – I really mean it and I have students from high schools who are taking my courses before joining universities
  • Without paying thousands of dollars – like you do for colleges
  • Without reading thick textbooks which has 1000’s of pages – which are good but they consume time 
  • Without spending thousands of hours for interview preparation through blogs & books – I have students from MIT, Stanford, IIT, Microsoft, Google, Apple, Cisco,etc who has used my courses for their interview preparation. 

About Me

I am Vignesh, born and brought up in Tamil Nadu, India.

I did Bachelors in Computer Science in the years 2010 -2014 from Velammal Engineering College. I worked for a leading MNC  for some years and in that process, I discovered my passion to teach students. So I resigned my job without having any backup in mind and started teaching students. From the very first month I launched my online course, I never turned back. It has been an unbelievable jouney sofar, training students in the field which I have been living with for the past 10 years. I always enjoyed Computer Science right from high school till today.

Most of my previous students think me as "genius" after attending my 50 hours courses. But the hard fact is I am a very slow learner. I am no where close to be called as genius. But I am a hardworker. I never get satisfied until I get the concepts and the reason behind these concepts. Having taken the hardest path possible to learn the concepts only through my hardwork, I believe I can explain the concepts in the simplest way possible so that even a slow learner like me will be able to understand it. Don't believe me ? I have trained over 20,000+ students in the past year across 125 countries and more than 95% of my students are very happy with my courses. I get appreciation messages everyday from students that they have used my courses to crack interviews, get good marks,get good jobs,etc. And many students of mine got themselves placed in top notch companies like Google, Microsoft,Adobe and they have used my course extensively in their preparation. This gives me immense satisfaction and force me to work even harder. 

I took Operating systems course by tutor vignesh. I really liked his way of explaining the things, all concepts so hard made all clear. Even after months of taking his course I still remember those. All because of the example and questions solved during lectures. Anybody thinking to have a good hold on OS for placements or for academia highly recommended.I am preparing for my job interviews. Taking these courses was very helpful.I am also planning to invest in database courses.

Vignesh has an in-depth understanding of the subject matter and explains everything in an easy and comprehensive way. He is approachable and addresses queries until the resolution has been reached. I have learned a lot from his courses and I want to take his future courses as well. He will be a great asset to the project he aligns too. Thank you Vignesh.

The instructor’s peculiarity is the ability to explain complex topics in simple and clear way, repeatedly returning to the already completed material and repeating the main aspects. The instructor’s aim is not to load you with a bunch of new information, he very intuitively dwells on complex topics and sometimes even explains in too much detail. In the case of operating systems, this technique is absolutely justified!
