during teaching such a nice smile on face (ماشاءاللہ) کمال است ❤️

[tinumeena]

Namaskar sir, first of all i want to thank you for all these informative videos. i have to say the way you explain every aspect, each term and everything in such a simple way it's just commendable.
Apne sab kuch itne ache se bataya hai ki video ke sth hi sb yaad ho jata hai aur zada se zada padhne ka man rehta hai.

[Physicsvideos-uevc]

Sir please complete this course. ☺️ its full of knowledge. we are interested in Full course of Quantam mechanics.

[samruddhiannasahebjadhav]

U r the best teacher in the world 👍 aapke teaching and explanation skill bhot acche he ....keep it up sir

[hasnainshabbir]

Sr please complete the series we are waiting for it's completion...
It's very helpful ...
