Hi!
You cannot get a degree at your convenience. You will only get it one year after the course is complete.

Yes, of course a distance degree from a recognized distance university is equally valued to a regular degree. The only difference between the two is, one is inside a classroom and one is inside a virtual classroom. A degree earned from Indira Gandhi National Open University or Sikkim Manipal University of Distance education is as valid as the degree obtained from any regular colleges of India. This is because both the universities are recognized by UGC.

There are various courses offered by Indira Gandhi institute of Aeronautics. You need to inform as to which course do you want to pursue so that information can be provided to you. Or you may log on to the website of Indira Gandhi Institute of Aeronautics at www.igiaindia.in for more information.
