Colleges in Delhi

Yes, a male candidate can apply for B.Sc in nursing in AIIMS.

Sorry, but many people are studying to become an engineer or doctor but what is a guarantee of job after 4 or 5 years, most important thing in airlines and aviation is that it is a growing industry. Nobody can stop you, if once you are skillful in your field. Just be confident

Yes, you are eligible for taking admission in B.Sc if you have completed Diploma in CE.

According to me, no. BBA in Aviation is not enough to become a pilot or to pursue a pilot training course, For the pilot training course, you must be a science student. Once you do pilot training course then BBA in Aviation or Diploma in Aviation would be an additional qualification for your promotion and all. http://www.distanceknowledge.com/2018/01/27/bba-in-aviation-operations/
