hello,

For becoming a pilot you need to enrol yourself in an aviation academy and for that you must keep in mind the following things:

• your age should not be less than 17 years to begin training
• You must have scored 50% in 10+2 which may vary as per the Institute requirement
• You must have studied MPC (https://leverageedu.com/blog/mpc-subjects/) [Maths, Physics, and Chemistry] along with English at the intermediate level
• If you are a non-science student, you may pursue the required subjects through the National Institute of Open Schooling or as a private candidate from the respective state board
• You will need a medical certificate.

So you see the question whether you can pursue maths through NIOS is answered in this. You can pursue the remaining subjects through NIOS board.

hope this helps!!
