I prepared for AWS cloud support associate by only watching your CN, OS playlists

I was a complete noob in these subjects but your teaching has helped me understand those subjects very well, and I managed to qualify in both the Technical rounds, but failed in the managerial round

Thank you so much Sir for all your efforts, this is coming from a student who got D grades in his semester exams of OS, networking subjects, but was still able to crack OS, CN rounds of AWS interview, you made me fall in love with subjects that were completely alien to me. ❤
