I have been using RTI for obtaining the information from NCERT regarding the NTSE , and i am very happy that NCERT has taken a learning from it, by declaring the marks of the selected and non selected students in the public domain.
However there are still lot of things which NCERT needs to do
1. NCERT should give the papers to students
2. NCERT should ask the states conducting stage 1 examination to do the same
