West Africa Senior High School missed an opportunity to make a second successive appearance in the semi-final of the ongoing National Science and Maths quiz after placing second to Mawuli SHS in Friday’s second quarter-final contest.

The Mawulians amassed 56 points to book a place in the semi-final at the expense of WASS (38 points) and Holy Child SHS (21 points).

The Volta Region side jumped into the lead at the end of the first round and they never let hold of their lead.

Represented by Ahianou Mathias Kwame and Amoah-Mensah Raphael, Mawuli School finished each round as leaders to make it to the penultimate round.

WASS had made it after seeing off Sunyani SHS and Bueman SHS at the one-eighth stage.

Earlier on, Prempeh College qualified to the semi-final round after beating GSTS and Aduman SHS.

They join Ghana National College, University Practice SHS and Adisadel College as the quarter-finalists so far.
