Enough to get a decent mark, if you are completely thorough with it.
Hello Anjhu. It is the minimum that you should study. Once you are thorough with it, you can read the remaining content form the text. Also diagrams of the NCERT Text is very important.
You’re right 😎

You just copy pasted Aman Dhattarwal bhaiya’s notes from YouTube. Atleast give him the credit.
Dear Respected Anonymous User, please read the following:
1. There are notes for chapters where an external link (http://priyankatyagikvs.blogspot.com/p/b.html?m=1) is given and no where it is claimed to be authored by me.
2. Notes prepared by me has an endnote with the author name.
3. The link given in the YouTube video description of the Youtuber, has given link to a website that again links it to KVS Biology Support Study Materials released in the year 2011-2012. So technically links for the Biology study notes are not of the Youtuber at the first place and rather it is from KVS.
I don’t understand why that over intelligent person said that in the first place. And, how you kept cool! Kahaan, kahaan se chale aaate haain. 🤦🏿♂️
