Cherry Lee:Both group and private tuition are equally good. It greatly depends on the preference of the child and which type of environment they are able to learn better and effectively.
I believe the main factor is the teacher...
Consider this.. if the teacher is good for 1-1.. but in a class setting he cannot address all the questions promptly for the students... then the students cannot benefit as much..
If the teacher is good for 1 to many.. but in 1-1.. he gets sleepy.. or is too strict on the child that affects learning... then how?
My nephew had this problem... he attended a tuition class.. had a very good teacher there.. and secretly hired him to teach him 1-1.. but in 1-1.. he wasnt' very effective..
Hope you can use this to consider... my 2 cents
