There are various aviation courses in the flying schools and you can choose any one, your college degree matters less.

The steps to become or make someone a pilot are as follows:-

• Get College Education in any discipline i.e. any course - Usually aerospace engineering, aeronautical mechanical engineering, physics or computer science provide a good educational base for pilots.
• Gain Flying Hours - Go to a pilot training school and get at-least 250 hours of flight experience.
• Earn a Pilot's License after 18 years of age - The applicant has to clear one written examination and a physical examination to ensure they have good vision and hearing as well as no physical impairments that might lead to crashes.
