NCERT (National Council of Educational Research and Training) is an autonomous organization under the Indian government that develops and publishes textbooks for students from primary to secondary levels. These textbooks are used by schools affiliated with the Central Board of Secondary Education (CBSE) and many other state education boards in India.

NCERT textbooks are known for their quality content, easy to understand language, and comprehensive coverage of the syllabus. These textbooks are designed to provide students with a strong foundation in various subjects and help them prepare for competitive exams.

NCERT textbooks are available in both English and Hindi medium and cover subjects such as Mathematics, Science, Social Science, English, Hindi, and Sanskrit. These textbooks are available for free download from the NCERT website in PDF format.

In addition to textbooks, NCERT also publishes supplementary books, teacher's guides, and other educational materials that are used by schools across India.

Overall, NCERT textbooks are an essential resource for students and teachers alike, and their quality and relevance have made them a cornerstone of the Indian education system.
