Shin Min Daily News reported that more than 25 Secondary Five students who were taking their O Level Mathematics Examinations were registered for the wrong test papers. The newspaper quoted a student who did not want to be named who took the exam at Ahmad Mattar Secondary School.

The students found out that they took a different test than the one they prepared for when they compared the subject code in their admission tickets with the test reference in the ten-year series. They were prepared for the 4016 Mathematics paper,s but sat for the 4048 papers instead.

It is believed that the school registered the students for the wrong paper. The 25 affected students told the newspaper that they found out from chatter in Twitter that students at Woodgrove Secondary School were also affected by such mix-up.
