Dear experts, I need a really good reply for this query of mine. Most of them tell that questions for the chemistry board exams usually come "just from the tbk" is it sufficient if we just be thorough with the whole tbk which includes the Numericals as well along with previous year papers or should we practice from a guide too?  

Hi,

I would like to suggest you for the preparation of board exams give first preference to the textbook prescribed by CBSE. All the concepts are very well explained in the NCERT textbooks. Go through each and every topic of the textbook thoroughly. Practice conceptual questions and numericals as much as you can do. Board question papers are completely based on the NCERT textbooks.

For better understanding of concepts of chemistry in different manner you can refer to the other reference books and study material present on our site. Kindly refer to the link of the study material given bekow :
