hi,

see in most of the airlines of india, generally candidates who have completed the pilot training course from tier 1 institute and have some internship experience may select in indian airlines, however it always good to have a graduation degree which is helpful for you if you ever decide to quite your job as a pilot or can not land a suitable job after completion of pilot training course, you may go bsc in physics or bba in aviation management, diploma/bachelors  in Aircraft Maintenance Engineering.
