Some 81.3 per cent of the 37,267 candidates who sat for last year's GCE O-levels scored five or more passes.
The Education Ministry in a statement on Thursday also revealed that 95.5 per cent of candidates scored three or more passes, while 99.8 per cent had passed at least one O-level subject.
The results were similar to last year's where 81.9 per cent scored five or more passes, 95.3 per cent had at least three O-level passes and 99.9 per cent passed at least one O-level subject. Students received their result slips from their schools on Thursday.
In an attempt to place less emphasis on academic results, the Education Ministry did not name top scorers for the O-levels, in a similar way when it did not name top scorers at the Primary School Leaving Examinations and the N-level results last year. In 2012, the three top scorers for O-levels obtained 10 A1s each.
