NCERT (National Council of Educational Research and Training) books are widely recognized and recommended for various competitive exams, including the UPSC (Union Public Service Commission) examination. In the field of Zoology, NCERT books can serve as a comprehensive and reliable resource for preparation. However, it is essential to understand the content and structure of these books to make the most effective use of them for exam preparation.
