Hi, I’m a kiasu newbie here.

Have been reading the posts and seen that mostly recommended CMA, 3G Abacus and Apple Plus.
My daughter is 4 yrs old and she has been learning abacus under Smart Brain and is doing fantastically well.
They have franchises all over the world and even help those special needs children.
They are different from CMA, 3G abacus and Apple Plus cos they use one hand only and it is super fast.
Just to share my view only.
