Hey,

Yes you'll get a chance to complete your further studies while being a part of Indian Army. Infact in NDA one acquires BA/B Sc, pre-engineering stream provides you B Tech studies. Even after joining technical arms one does an engineering degree. Also, you can pursue a discipline of your choice during paid study leave of two years granted during mid-career, normally after unit command at Colonel’s rank. Technical officers are given an opportunity for post graduation like M Tech courses at IITs.

Hope this helps.
