hello sameer

firstly thanxx for asking the question.

NTSE i.e. National talent Searched Examination is an examination conducted to award scholarship to the deserving candidate/s studying in Class X. The student applying for this examination need to be of a recognised school but no where mentions that the exam is given via school. Thus, you can apply for this exam outside the school too.

Hope the answer turned helpful to you. further you can visit the given link: https://mypat.in/ntse 

Hi Sameer,

One needs to apply separately for NTSE examination and not via school.

Hope this answers your question.
