Probably because of British influence, private tutors are a commonplace in India. Being raised there, my parents though encouraged me to just work hard myself and not rely on external tutors. There were, however, a few years where I did get tutoring for a few subjects that I needed help with- and my experience has been great! Especially, for the 12th standard (high school) Physics where I got >90% in the board exam. The tutor knew his stuff and the pattern of the 'board exam' well.
On the other hand, I have had peers who rely on private tutoring almost entirely and almost neglect what is being taught in schools. And I have known parents who see schools as a necessary evil.
There is also, the world of preparing for 'entrance exams' (including IIT-JEE) which is where I have seen tutoring to the extreme. Students who 'drop-out' (still enrolled on paper but not attending in-person) of regular school starting as early as 8th standard (grade) and move to cities where there are mini-economies based on such preparatory institutes. They only go back to their home-towns to write the final exams which is usually subset of what they would learn at the institutes anyway. But the sacrifice they make to be away from family for most parts of the year and the hours they spend staring at a book is admirable.
Note: Please don't take this as a generalization of what happens in India- just what I saw growing up in New Delhi.
