Hii Shreyas,

Hope you are doing well.

(NCERT) conducts the NTSE exam every year and 1000 meritorious students are selected for the NTSE scholarship. It is based what the students score and no other conditions are kept in point.

NMMS disturbutes  INR 1000 per month, to the selected students. Under National Means-Cum-Merit Scholarship, the scholarship amount is paid by State bank of India (SBI) on one go.

Both NMMS & NTSE are not the same.

NTSE is a scheme to identify talented students from Class 10 for scholarship with no conditions. Whereas  National Merit Cum Means Scholarship scheme, it is proposed to award one lakh scholarships to meritorious students from Class 9 whose parents' annual income is not more than Rs. 1.50 lakh per annum.

So, you can avail both the scholarships together. Availing each won't affect the other.

I hope, now you are clear with your doubt.

Best wishes for future.
