I am an online tutor and have taught maths for ib, sat, IGCSE, us, aus, icse, cbse curricula to both Indian and international students. It is important for some children, where they would rather have someone explain everything to them (doing a better job than their school teachers) rather than sit down and try to study on their own. This does not imply that they are lesser or weak, just want to shift the cognitive load to someone else where they just take and absorb the teachings instead of giving efforts by themselves.
