Hii,

You have PCB and Maths as your 6th subject, which is good. But to become a pilot, Maths and Physics should usually be part of your main 5 subjects. If Maths shows up in your main marksheet like other subjects, some flight schools might accept it. But if it’s shown as an extra subject, they may not.

Rules might change in the future, but it's better to plan based on the current rules. If needed, you can give Maths again through NIOS or a similar board to make it count as a main subject.
