Hello,
I am attaching a link that will give you all the required information about different eligibility conditions for NDA. https://www.shiksha.com/sarkari-exams/articles/nda-eligibility-criteria-blogId-22425
I think you are outside the zone as those born before 01 July 2001 are not eligible. But go through the information once again. Best wishes to you.

Because you have not written about the subjects studied at graduation level. However, the eligibility criteria of KVS PGT is given below for an assessment. PGT Biology Eligibility: Master's degree in Botany/ Zoology/ Life Sciences/ Bio Sciences/ Genetics/ Micro Biology/ Bio-Technology/ Molecular Biology/ Plant Physiology provided they have studied Botany and Zoology at Graduation level and B.Ed. While for TGT Science require a Bachelor's degree in Botany, Zoology, and Chemistry+ B.Ed.

You can try for government jobs or go for Diploma in this same line.
