I just want to say to the critics over here that everything is not possible.... You want chapter in 20 mins then also want to cover each and every topic... This is a video for revision of the chapter and this is the best waynof revision. Go and first read the chapter in detail and then come for a revision 💢😡
I understood this chapter very well, but for quick revision I watched this video.And now I'm completely confused .this teacher has confused all my concepts.😅🥲
