How good is IGNOU for MA courses?

It is guaranteed that the study material provided by IGNOU is excellent. You'll have a great time going through them. It will undoubtedly provide you with a thorough understanding of the subject. However, it is not without difficulty. You get to work hard. If you want to study Economics via distance education, IGNOU is your best bet. 

However, pursuing it at a regular university in a face-to-face mode may be preferable because teachers can assist you with your difficulties. However, if you are already employed, MA in Economics from IGNOU is an excellent choice.
