Hi Bhagyashree,

Candidates with a b.com degree are also eligible for giving CDS exam.

But they can only apply for IMA or OTA posts and not for AF or INA.

Also, being a female candidate you can only apply for Officer's Tranning Academy  (OTA).The age limit for this is between 19 to 24 years too.

So, ultimately yes you can sit for the exam even with your b.com degree.

Good luck.
