Value added by tuition: A better way to gauge

As alevel is easier than school internal exams, students often improve by 2 to 3 grades from their prelim results even without tuition.

So how to better gauge the value-added by tuition? Using percentile improvement is one way.

Student started tuition after failing J1 MYE. He improved from lowest banding to highest banding by J2 MYE.

1.Student scored 16 percentile in school internal exams before joining tuition.Her school distinction rate in 2018 is 68%. So to be on track for distinction, she has to improve to at least 32 percentile to get A in alevelStudent got A in alevel. So there is value add of at least 16 percentile.
2.Student scored S grade in J2 MYE before joining tuition.S grade is around 20 percentile in her school. Her school distinction rate in 2019 is 65.5%. So to get A, she must have improved to at least 34.5 percentile.Student got A in alevel. So there is value add of at least 14 percentile.

Percentile improvement is not easy to achieve. Imagine running the alevel marathon, one has to overtake more than 16% of people along the journey to get A.
