Do Indian journals represent the quality of Indian universities?
Scammers appear in all nations, I'm afraid.  In addition to the Indian predatory publishers, I receive lots of spam from Chinese, German, and American predatory publishers, plus I'm sure from many other nations that just aren't coming to mind.  Just as I wouldn't judge American scholarship from the spam I get from American publishers, or from the diploma mills that operate there, so I would not judge Indian scholarship by the fraudsters of India.  It's just a large nation with an open society and a good information infrastructure, and so a certain fraction of scammers are to be expected.

Now, there are other aspects of the Indian school system which merit concern, but the publishing scams should not be the basis for any opinion that you hold.
