Jasmine Thoi, 14, has tuition outside school for her two strongest subjects, Chinese and Maths - even though she already gets As in them.
The East Spring Secondary student is among a rising number of youngsters who are opting for tuition, regardless of how good their scores may be. She said: "Tuition lets me explore more and learn faster than my friends."
Even students at tertiary level are getting in on the act.
Ms Vivian Koh, 20, a first-year social sciences student at the Singapore Management University, will start tuition this week for a calculus module.
"We're learning so fast in university," she said. "I'm not good in maths so I'm lost in class."
A week ago, Senior Minister of State for Education Indranee Rajah told Parliament that tuition for children who do well is counterproductive.
But tuition is not just for the weak and struggling. Many straight-A students are seeking help so they can maintain their standards or do even better.
