No ,you are not eligible for NDA.

This is because,

the upper age limit to be eligible for NDA examination is 19.5 years but you are 20 years old

NDA eligibility criteria says that:-

Thank you

Dear Aspirant, sorry to say as you are not eligible for NDA exam 2022 as you are already 20+ and the maximum age limit for NDA is 18.7 years. But if you are desperate to join Army then you can opt for CDS after your graduation. It is similar to NDA. I hope you are clear now. If you have any other queries feel free to ask. All The Best!!!
