Dear aspirant,

See I myself was a jee aspirant and clear jee mains and got into nit jamshedpur. So what I used to was, I prepared short notes from the ncert chemistry textbook specially for inorganic chemistry.

For s block or any other block chapters you need to be full thorough with ncert chemistry. The equations like of Washing soda, caustic soda are very important for jee mains.
