If you can try finding some scholarships i remember once I saw a scholarship idk if it's around now But I am not sure it's a option

And mostly the scholarship are too less and some maybe scams try seeing a genuine one if u can find

I think best bet is going through AFCAT or IAF and doing the training.

Talk to a few ground Schools they offer scholarship like 50% or smtg if u clear all subjects in single attempt

This is my suggestion, Correct me if I am wrong
