Hello Aditya,

To take part in CDS entrance exam you just need a Bachelor's degree in any recognized university for IMA/OTA and for INA you need a Engineering degree from any recognized university and for AFA you need a Engineering degree as well as Physics, and Maths, in 12 standard.

And with B.pharma degree, ofcourse  you are eligible for IMA test as he need only graduation degree. In IMA they train only cadets to become an officer in Indian Army they don't train medical like post. For the post of Pharmacist you need to clear the rally of Indian Army soldier Bharti where you can become soldier pharma, your age limit should be 19-25, 10+2 pass and B.pharma degree with 50% marks to fulfill the criteria of eligibility.

All the best!!
