While a score of seven points out of a maximum of 42 in Hong Kong’s Diploma of Secondary Education (DSE) exams might seem low to some, for non-verbal student Tam Chun-yu it is a massive accomplishment, achieved by typing his answers with just one finger.At the Hong Kong Red Cross John F Kennedy Centre, Tam, 20, was among candidates receiving their DSE results on Wednesday, securing level 2 passes in English, Chinese and information and communication technology (ICT), and a level 3 in Chinese writing.Tam achieved these results despite living with severe cerebral palsy and spastic diplegia – conditions that have steadily worsened since high school, progressing from a walking disability to severe spinal curvature and speech difficulties.Relying entirely on a carer, he must use a specialised table and supportive aids attached to his wheelchair just to maintain a proper posture. Yet he still successfully completed all six exam subjects using only his index finger.Because of his physical limitations, Tam applied for special exam arrangements, including typing on a smartphone notes app, using a computer, and being exempted from up to half of certain exam papers.He was also allowed to take a five-minute break for every 45 minutes of exams, during which his carer could enter the hall to adjust his posture and massage his stiff hands, back and neck.
