Hello,

You're eligible for Ground Duty(Non-Technical) Branch if you have passed graduation with 60%, all other post in AFSAT specifically asks for 60% in Maths and Physics at 10+2 level, which I don't think you qualify since you mention that you have completed your 12th Standard in Arts Stream.

Now, coming to CDS, you're eligible for Indian Military Academy with age limit being 19 to 23 and Officer Training Academy with age limit being 19 to 24, other posts ask for either PCM at 10+2 level or graduate in Engineering.
