THANKS FOR THE A2A
YES there are many youtube channels for physics and chemistry for NEET
Physics – u can subscribe Etoos but it’s quite costly(videos are too good) , so subscribe only selected topics. I found some lectures of NV sir on rotation, waves, optics, electromagnetism, electrostatics etc illegally posted on youtube(full chapter). Check them. B M SHARMA videos are also good but post NEET standards.
Chemistry – ATP (any time Padhai) academy videos by Vineet khatri sir are toooo good for organic chemistry(free) , practical chemistry etc. I think for inorganic byheart NCERT. Physical is logical and NCERT knowledge is enough.
Biology- Free videos of Shomu biology. But do not go too much out of NCERT, some medical aspirants are too much interested in biology and spend too much time on it
PS: One of the advantages of these videos is that u can tap up ur teacher at late nights and ask him to repeat the lecture! U may find urself sleepy some times(even after adequate sleep) , no problem, open youtube on ur mobile, increase brightness and start watching these videos. Ur sleep is gone, believe me I have experienced this myself!
