hi,

see airport authority of india recruits for ai traffic controller post, the eligibility criteria is candidates from any of the btech course graduate or b.sc graduates with physics and mathematics are eligible to apply.  admission is based on the selection of candidates via online entrance test which followed by interview. air traffic controller is responsible for the sending the signals to the pilots or near by air ports to safe landing and departure of air crafts. the beginning of the professions candidates are trained. generally there is 5 days working and there is random shifts, also the job is transferable to one airport to others.

salary is ranges from 40,000 initially, however since its a government psu job, the job is secured , however the growth is moderate and there is also health and other benefits.

I think that your percentile is low for selection, but definitely you can practice more and try again next year. Proper practice and dedication will definitely lead you to a good college. Advance is a difficult exam and most students dont get selected in one go. Try again

All the Best!
