Hi, the tentative dates for admit card is between 9th October to 15th October. The NTSE 2021 exam will be conducted on October 24, 2021.  Since, your stage 1 exam is conducted by the state level board itself. Stage 1 exam will be taken before stage 2 NTSE 2021 exam. You do not have to worry about about your 2 exams clashing it never happens. Everything will be looked after by your state board itself and you will have enough time to revise whatever subjects are for your boards exam. Hope this helps. All the best!
