Actually I was searching for these comments that whether student's doubts were cleared or not! I'm glad that I found this comment! Now I'm at 18th minute , Lemme see the whole video with focus and I will come back again !
Heyyy sir I just completed my class 12.....but I still remember how I used to watch these 95+ series on the premiere....im so glad that I found you on TH-cam and with your help I got 90 percent in 10th. I will never forget you and your teaching in my entire life....I will stay your subscriber through the entire time and will watch your video in future not for studying purpose but to remember how hardworking a man can be.....thank you so much for everything
@akshatagarwal3917 Bro wasn't it like general promotion for that year? 😂😂I was also in class 10th that time and I got 97% in Boards.Though I studied hard but we all know deepdown that the exam was not conducted and hence we were kinda general promoted. 🥲
Electricity and light are the two big and the most important chapters of science in physics, also CBSE did'nt delete any portion from these chapters for boards

Really very smart and hardworking teacher sanjeev sir is ..... ❤️ There are some teacher who just read books but he is the one who tries to make our concepts clear .......

Sir, Full length is good , because if we want revision and we are not prepared so we don't have to search for the parts of video..... In a single video itself, we can study by dividing the video according to us......
Dude but if you are revising a chapter you’ll not revise the parts of it right? If you are revising the parts of it then you are not revising the whole chapter. And bro if you’ve not prepared how will you study the parts of it😂. F in chat
Full length videos are more convenient as we can find the whole chapter together which maintains our focus and sometimes it's hard to find the other parts too.
@@rajatdeswale91 he is the man who give all of us education in these pandemic days with crystal clear concept clearance that's not a problem of earning money it's not important than our education 🤨☺️

sir full lecture is perfect....especially the 95+ series. we are blessed to have you as a teacher.... :) and the way u said that we have to prove tha lockdown is a boon in bane was fab.. bless us all
Right now, I'm in class 12th, when i was in class 10th i read whole science from you Sanjeev sir and i scored 89 in just a days🙏.. I'm gland that TH-cam recommended this after 3 years.. legend Sanjeev sir 🙌🙌
When light travels from rare medium to denser medium , the refracted light bends towards the normal and angle of Refraction is less than angle of incidence
This chapter is so long and thos teacher here is teaching so well! As a person who don't like physics it's really good to study here not. To mention I find it easy
