Hello Sunidhi,
The cutoff for the Class 6 National Science Olympiad (NSO) usually varies each year, depending on exam difficulty and student performance. For the 2024-25 exam, it is estimated to be around 40 marks, though official confirmation will be available with the results. The Science Olympiad Foundation (SOF) typically releases answer keys a few days after the exam, so you can expect the answer key for the November 12 exam (Set B) to be available shortly on their official website. Keep checking there for the latest updates on answer keys and cutoffs.
