The competition, meant for children in grades six and seven, will see the first round held at KinderWorld’s Singapore International School in the four cities on April 24, according to the organisers.

The top qualifiers from Vietnam and the rest of the Asia Pacific region will go to Singapore for the final round on May 29.

The event is organised by the KinderWorld Group and Singapore’s Hwa Chong Institution. The first event was held in Vietnam last year.
