Skye had to miss four months of school this year as a result of a liver transplant.
By the time the 12-year-old returned to school, he had two months left to prepare for his Primary School Leaving Examination (PSLE).
He said: "I was scared. I did not want to be left behind." But the time he spent recuperating did not go to waste.
He was busy doing test papers and reading up on the topics that he was missing out at school.
His father, Mr Poh Leong Teng, 36, a supervisor, said: "He would revise his work every day, even when he was recuperating." Skye also spent time on his weakest subject, Mathematics.
"I memorised all the concepts and wrote them in a book. "I also called my friends if I needed any clarification."
Skye said that whenever he felt anxious, he would take a break and watch cartoons.
He giggled before saying: "My favourite cartoon is SpongeBob SquarePants." When The New Paper visited him at Bedok Green Primary School on Friday, he was all smiles.
"I've reached my target score of 180. "I am very happy with my results." He scored an A for Chinese, B for English, C for Science and D for Mathematics. His mother, Mrs Joanne Poh, 36, a housewife, said: "I am so proud of him for trying his best."
When Skye was six, his mother explained his condition to him.
