The results of the high-stakes primary school leaving exam, which students sit aged 12, came out last two weeks.
The test determines a child's path in the competitive school system and has become a source of stress for many.
But a call for people to share stories to show how exams don't need to decide your future has sparked an outpouring.
Over the weekend hundreds responded to Khairudin Aljunied, a local university professor who said the move would give young children "hope and motivation".
"My PSLE score is 221. I am now an Associate Professor in a University," he wrote.
Athletes, teachers, engineers, entrepreneurs and a member of parliament all followed suit.
