Legon-based giants, Presec have crushed defending champions Achimota School in the ongoing NSMQ Greater Accra regional championship.

The hosts put up a strong and challenging performance from start to finish but they still fell short of beating the five time national champions.

Our Lady of Mercy (OLAM) SHS and Ghanata also featured in the contest but were both overshadowed by the two top-dogs.

Presec will face Tema-based Chemu SHS and the winner of the last contest of the Day for a chance at the ultimate.

The 27th edition of the National Science and Maths Quiz, meanwhile, come off in May at the University of Ghana, Legon.

All schools participating in the regional championship have qualified for the national competition either by being seeded or via regional qualifiers.
