NIOS is a recognised educational board, following its own set of books and curriculum. The books prescribed by NIOS are closely related to the NCERT framework and are similar to the CBSE books' contents. However, students from Class 11 and Class 12 must focus primarily on the books and resources based on the NIOS syllabus . While CBSE books can be helpful, students can focus on their preparation with the NIOS books.

Hello dear student,

If the word that is NIOS board have provided you with some specific or different books than CBSE books of 11th and 12th then according to my opinion we should go for those books and by them the syllabus don't be much different as NIOS is also a recognised board and equivalent board to CBSE. Sudesh no need to worry about it. While to appear in the exams of NIOS that is board exams you should buy NIOS books when we can prepare for neet considering NCERT books for CBSE books. Books for NIOSand CBSE are same then there is no problem.

Best wishes
