Excerpts of the tale:
It happened after the Mother Tongue (Tamil language) exam was completed in a school in the northern part of Singapore in early October.News Link
The Ministry of Education and the Singapore Examinations and Assessment Board (Seab) confirmed the incident in response to queries by The New Paper.
It is not known what prompted the tampering. The Corrupt Practices Investigation Bureau (CPIB) is now conducting a probe.
In a statement to The New Paper, a spokesman said: 'CPIB has interviewed teachers and relevant persons involved and investigations are ongoing.'
Markers at Farrer Park Primary School, which was a marking centre for the subject, found that the answers in a composition paper of a pupil had been partly altered.
When the markers tracked down the pupil's Paper 2, they found that some answers in the fill-in-the-blanks section had also been cancelled and replaced with other answers.
It is understood that the pupil was given 10 marks for the section when he or she would otherwise have scored zero, an anonymous source said.
A thorough check was done and similar changes were found in the Paper 2 transcripts of two other pupils.
The anonymous caller who alerted The New Paper said: 'You could tell it was an adult's handwriting. It was even written in a different shade of blue from the pupils'.
'It looked like the answers were scribbled in a hurry.
'Even if you didn't understand Tamil, it was very obvious.'
Had to be Tamil hadn't it?
