How can i study for pilot ????

To become a pilot, you have to go to school that offer the program you are looking for. There are some that just focus on aviation. When I went thru this process, I took a couple of visits to see which one fit my needs. Depending on your school, they usually start off with ground control then single engine then you work your way up to commercial airplanes. If you can get into the air force academy, I would suggest that route. Good Luck!
