During the school closure   3-16-2020- 3-27-2020 kindly check this page frequently. I  posted the Notes for 5-5 FIRST part only as per YC direction we are omitting the otherpart for now. If you need my help kindly email me with your  personal e-mail ID and your phone number.  Chapter 6 we have to do at least FOUR sections, which I will try my best to do in videos.
