TESTIMONIALS

Hear it from Your Peers

  • Thank you sir. You have made DSA with Python least complex for me😅. The course is very good for beginners like me. I loved your way of teaching and the way you explain things. Thank you so much sir.
    Parv Singhai
  • You are a great teacher. I am attending your A1 batch where we have covered basic to advanced Python topics with over 150 questions, as well as DSA with over 300 questions. Your teaching style is fabulous, making it easy for everyone to understand the problems and how to solve them. You are always supportive, like a big brother, and you come to class 30 minutes early to clear any doubts, whether they are related to the class or not. Thank you for your dedication and guidance.

  • Today I am glad to write this feedback message as our course has come to an end. I would really like to appreciate your hard work you have put in these 5 months in betterment of the students. Had only little knowledge about python but understanding it in depth and clearing DSA concepts is possible only because of you.

  • def feedbackForAnirudh(): for i in range(1,1001): print('This is awesome course.') Thanks a lot Anirudh for such a knowledgeable experience. I got to learn a lot of things. Moreover my fire to upgrade myself was reignited. You explained the things in the easiest way possible and taught us like a friend. You made sure that we don’t hesitate a little in asking any questions. We will look forward to you for more guidance in future and will also look out for any relevant courses you will be facilitating. Thanks a ton again and looking to be in touch in future.
