Hey, I can aid you with the perfect answer.

You didn't mention where you are studying your 12th grade. Let me elucidate and clarify in every chance.

If you are studying your 12th-grade in UAE then you are obviously eligible for the DASA/CIWG schemes. I.e. You can apply for both the DASA/CIWG 2018-19 according to the updates of DASA/CIWG.

If you left UAE after finishing 12th grade and doing 12th grade aside from India then you are surely eligible for DASA. I.e. You can apply for DASA only.

If you are studying 12th grade in India then you won't be eligible for both the DASA and CIWG schemes.

Good luck.
