Our Son just started with OWIS Nanyang Campus this Year, presently is going in Grade 1 Called P1.
we have been happy with all his previous schools- kindergarten and play schools and we feel he has had a good base.
Continuing on it he seems to enjoy his time in OWIS, it is a different curriculum from what i had in my time, but am happy with the hands on approach and integration of the subject (i believe it is similar in most of the international Schools).
Well i cannot compare to other schools but it is suitable on the pockets as the cost is relatively low and quality of education till now seems to be good so complains from my side.
They do tend to have a lot of interaction and parent involvement which can be at times overwhelming specially when you Kid expects you to be there every time.
But all in all Value for Money :) ....
All said and done Money is important when it comes to education in Singapore which is in terms cheap.
