English notes of class i.sc second year about CBSE board
Hii!
Sorry, but you don't get notes as such for an entire book on any portal. The best you can do to get notes and understand the textbook better is to purchase the reference books or the guides which are available in the market. These books contain, the explanation of the chapter, the summary, plot, in text and chapter end question answers etc.,
Hope this helps.
Good luck!
