Hey Udhaya,

NTSE (National Talent Search Examination) is conducted by the State Government and NCERT for class 10th students. You should be the student of Class 10 to be eligible to participate in NTSE.

For NTSE, all the syllabus (Science, Maths, Social Sciences) is from the NCERT Curriculum of 9th and 10th Standards.

So you have to read only NCERT books for preparation of NTSE. You should also have basic knowledge from previous standards so as to make your base clear.

Hope that this is the required information you needed.

Good luck with your preparations!!!
