Initially, @GiggleAcademy tried to start with the 12 year old who never went to school, but found they are all at different levels. Then we said let's start with Grade 1 English. But still found there is no baseline. So, we said let's start with the 2 year olds, when they just start to learn and grow with them year by year, for 16 or 60 years. Whatever it takes.
So, the current content is targetting 2-5 years olds.
