i am in class 10th. i want to be an international pilot, what courses are necessary after 12th or 10th please help me.

to become Pilot you must have Science at 10 + 2. And one more thing Commercial Pilot fees Cost more than 21 lakhs . So First check Whether it is Affordable for you or not.

I understand your objective, but then it is always beneficial if one completes graduation first before venturing into a specific field.
