Dear Candidate

Yes, you can apply for both NTSE and NSTSE at the same time in your 10 th class but the the thing is you need to score atleast 60 percentage of marks in your previous year annual examination that is ninth standard for appearing in NTSE examination in your 10th standard but for appearing in NSTSE you can be any standard which is starting from second to tenth standard and in intermediate also. So, yes you can apply for both of them and you will be having your 10 th examination as well unlessyou dont fell it as burden.

Hope this Information is helpful.
