Many are seeing double at the Nanyang Technological University's convocation ceremonies - with eight pairs of twins graduating this year.
They include the four pairs pictured on the right.
Ms Wong Jyun Yir and Ms Wong Jyun Yao, 23, are graduates of NTU's maritime studies programme from the School of Civil and Environmental Engineering and are now working in the same mining services firm Orica.
In their freshman year, younger sister Jyun Yao was hospitalised for two weeks due to a liver infection. She found strength in Jyun Yir's support.
The other three pairs of twins in the picture are graduating from the Nanyang Business School.
Mr Alphonsus Seng and Mr Alphonso Seng, 24, were reunited in the school after studying at different secondary schools and junior colleges.
While Mr Liu Zongli and his brother Liu Zongsheng, 24, are in the same school, they pursued different interests.
Zongli was more focused on learning more about investments and finance while Zongsheng was more active in student clubs such as the NTU Lifeguard Corps.
On the other hand, identical twins Loh Yun Xuan and Loh Yun Xian, 25, not only look similar but do almost everything together as they share similar interests.
Both attained first-class honours for their double degrees in accountancy and business.
The four sets of twins are among the 9,000 NTU graduates who are receiving their bachelor's and higher degrees in 18 convocation ceremonies that will end tomorrow.
They make up the 25th class of NTU graduates since the university was inaugurated in 1991, with the merger of Nanyang Technological Institute and the National Institute of Education.
