Hello,

To join the NDA (National Defence Academy), you are required to appear for an entrance exam conducted by UPSC. For the Army wing, candidates can apply with any stream, including basic mathematics. However, for the Air Force and Navy wings, Mathematics and Physics are mandatory subjects in your 10+2.

Even if you're considering basic mathematics, it is advisable to take Science subjects, especially Physics and Chemistry, if you're aiming for the technical branches or Air Force/Navy wings. In addition to core subjects, improving your general knowledge, English, and reasoning skills is essential, as they are part of the NDA written exam.

If you're focused on the Army wing, a combination of basic mathematics with subjects that interest you can work, but opting for advanced mathematics and science will keep more options open for all branches.

To join the Flying branch of the IAF, you must choose both Physics and Mathematics which is standard Mathematics. The third subject could be Chemistry or Computers or even Biology .

you need to take competitive exams like the NDA (National Defence Academy) or other entrance tests for the IAF in which solid grasp of standard mathematics will be crucial.
