Your OS and CN playlists were a lifesaver during my 6th semester! Achieved a GPA of 3.99 out of 4.00, thanks to your excellent teaching. You're a blessing, and I'm truly grateful.
I've just noticed your caption in English is also accurate. It's very useful in making notes. I am very grateful to have found your channel it has helped me a lot in my MCS studies.
Congratulations Varun sir, I just watched that this video got 1M+ views, really thankful to you for helping me since 2nd year till 4th year of my college.
