Hi,
Aptitude tests are in no way the be all and end all when it comes to selecting pilots from what I can gather. I have heard shocking reports about heavily selected pilots in the UK going from zero to airline; they give a general outline nothing more nothing less in my humble opinion.
If you want to be a pilot, give it a go. Fly a light aircraft – do you enjoy it? Are you any good at it? Then if you like it worry about training etc.
With regards to your personal situation, have you got some money behind you? I don’t know what nationality you are, if you have rights to work in India it would be a definite bonus. You could tailor you training with where you want to work in the end / where you have rights to work. But first things first, do you enjoy flying aircraft?!
