12 pairs of high-school seniors are about to graduate from one Georgia school. The 24 seniors at Brookwood High in Gwinnett County are a mix of identical and fraternal twins.

Fox 5 in Atlanta reports that as unusual as the circumstances are, most of the twins themselves find their situation to be perfectly normal.

"It's actually not as weird as people think it is," said one of the twins, Ashley Rivas-Triana. "Like a lot of people are like, what does it feel like? I just have a sister. It's not like we're some sort of alien species or something,"

There's even a set of identical twins playing for the school's softball team. Coach Kent Doehrman says when he called one of the girls into the game, both would respond. Courtney and Caroline Erickson offered some solutions, including wearing different colors and ribbons. "Well I'm color blind so that didn't help," Doehrman said.

Still, it turns out there's an even larger class of twins at Niles West High School. The Chicago Sun-Times reports that the Illinois school has 14 sets of twins in its sophomore class alone. The twins there are also a mix of identical and fraternal. Student activities director Jessica Ogulnik gathered the students for a photo. Though, she admits getting them all in place at one time wasn't easy.

"One day a member of the sophomore class came to me and said 'I'm a twin, and there seems to be a lot of us,'" she told the paper. "It took two tries, but the second time was a charm," she said.

There are a number of sites dedicated to helping potential parents conceive twins through the medical condition known as hyper ovulation. Fertility drugs are most commonly associated with twin births, though the statistical probability of conceiving twins increases when a woman is in her late 30's and early 40's because of the increased speed of ovulation, according to the site Twin Pregnancy and Beyond.
