The Falconets won their second friendly game 4-1 on Thursday during their South Korea tour.
The Falconets play their first match of the Fifa U-20 Women's World Cup on August 30.
The girls were too much for Widek Univeristy female team in a warm up match played at the Namhae Public Stadium in Korea.
Ebere Orji, Charity Adule, Chisom Henry and Azisat Oshoala got the four goals for the Nigerian team.
Florence Omagbemi, former Falcons captain and now the team's assistant coach commended the level of the opposition.
"It was a good game for our team and a good build up to the World Cup," Omagbemi said.
"So far we are satisfied with the sides that we have played since coming to Korea," explained Omagbemi.
The second string team was fielded by the technical crew unlike Tuesday's friendly which was to gauge the strength of its bench.
While comparing both matches, Omagbemi said the girls are good technically but not tactically better than the boys.
"But they should be hailed. They had a good goal which could have beaten any keeper. Also do not forget that all over the world boys are better than girls in football," she added.
The friendly produced a yellow card collected by the Koreans.
Nigeria's next friendly comes up on August 13.
