Is it advisable to go for a course offered by Dravidian University DDE ?

Distance learning courses have always been a strict 'no-no' in my textbook. They simply do not have the necessary academic nuance to help a student in any major cause. In most cases, you could learn the same knowledge by simply reading a book or taking up a free course on the internet. What do you need a special course for? If distance learning is the only option, I'd advise you to choose IGNOU as it is more widely accepted in the industry in general.
