NCERT EXAMPLAR QUESTIONS BOOK-PHYSICS,CHEMISTRY AND MATHS

Friends,

I think all of you are aware of the existence of a book called "Exemplar Problems", that is published by NCERT. Also, It is one of the prescribed textbooks in your 12th syllabus for your exams. Despite being a prescribed book, many were unaware of this book until last year board exams.

Last year Maths question paper, which were described by many as "One of the toughest question papers of this millenium", had a large amount of questions that came directly from NCERT Exemplar Question book.
After seeing that the CBSE took many questions directly from this book, the demand for the book has increased sharply.

Though we can't assure that the same happens next year also, it's good to have the book with you, as it has questions that are of a higher level than that given in NCERT texts. The book is also good for your Engineering Entrance exams, as it helps you to brush up your knowledge.

Here I am providing the links for the book-
