Hi,

Yes, you are eligible to fill the application form of NDA if you have passed your class 12 or are appearing for it.

If these are your marks scored in class 12 examination, then you can go for technical entry scheme in which Indian Army releases the merit list regarding cutoff of students. These students do not have to appear for the NDA written exam . They can just appear for the SSB interview.

TES does not apply to Air Force . Also,the cutoff for TES (Technical Entry Scheme) is  high (above 85% ) as the applicants are many and seats are less for TES.

For , detailed information regarding the exam pattern, syllabus, interview process, refer to the following website:
