My teacher has completed whole syllabus of 2nd book in just 10-15 days .....and now I'm here making notes of pw and clering my concepts thankuhh a lot 💫 sir ❤️🤗
Those who want to do something in their life this is the best 👍👍 platform for them. Here you will get each material to build up your concept and strong your base and the rest depend upon you how you work hard 💪 for this. All the best to everyone
Smile automatically comes at 38:40 after hearing one of the Greatest physicist name and also because in future both of them were going have Special talk for us..
It was since class 11 that I have unclear vision of emission and absorption spectrum. But today it was you who cleared the concept. Thank you so much sir❤🙏🙏
Sirji u light up my *physics* like nobody else The way that u *teach* over here makes me overwhelmed And when u *rock* on the board it ain't hard to telll U don't know oo oh...u don't know u r *saviour* ... oo oh oh that's what makes u *saviour*.....♡♡♡ Thank you sir....for all ur efforts♡♡ WE LOVE U ♡♡

Sir you are the best. I am preparing for NEET2020. I was very in physics but now for watching your videos my physics score is increasing. This selfless act of yours is very helpful for students. Wish me luck for my NEET2020. I hope this year I will be in aiims.
Now, physics have become my favorite subject by watching ALAKH Sir' s absolutely free lectures ............😍😍☺👍👍👍👍.......... And who watching this lecture in lockdown ?? THANKS ALAKH SIR Thankuuuu ,so much
5 YEARS AGO HE STARTED WITH A WITHBOARD , MARKER AND CAMERA AND NOW HE HAS A OFFICE OF MORE THAN 100 STAFS AND TEACHERS . THIS SHOWS HARDWORK IS ONLY KEY TO SUCESS
Sir your technique of teaching is awesome specially this our mind becomes fresh when you sing and clear the board. 👌👌👌👌👌 Who agree with me 👍👍like it... And comment...
As a MSc Student, I taught nobody will teach physics better than ALAKH PANDEY SIR❤.....He proved that degree 🎓is just a piece Of paper...A college drop student can be a best teacher also❤🙏
Alakh sir (Physics) & Ritu Rattewal mam (Bio) r the greatest teachers of our time!!!🤩🙏🏻👏🏻👌🏻 Tqsm for making us feeel the concepts! Never get bored seeing ur videos😄
He is Very best physics teacher ...I have ever seen.... really appreciating his work for students.....his lectures are so nice 🙂❤️❤️.....thank you sir.... always in debt of you 🙏🏻🙏🏻❤️❤️
I have studied chemistry atomic structure and watching this lecture is so amazing to mee I felt that sir could say that I have teached in chemistry but sir u completed once again🙏🙏🙏 and even every lec have previous lec revision 👍👍👍👍 thankuuuuuuuuuu so much sir for your efforts ❤️❤️❤️🎉🎉
Sir I was struggling with this chapter since a month but after watching this video of yours this chapter feels like a cake walk for me . Thank you so much 🙏
