How is TScore calculated for each subject?
We apply the following formula:
T=50+10 (XY)
Z
Where: X is the pupil’s mark for the subject
Y is the average mark (mean) scored by all the
pupils
Z is the spread of the marks around the
average mark (standard deviation)

The Mean score and Standard Deviation are only known to the MOE. Hence, you can only estimate them. Average Mean Scores is probably around 80. While SD is around 10.

Re: how to calculate t score
Mean scores will differ for different subjects, so will the SD. For the more difficult paper, mean score can be lower. Depending on the cohort "quality", the SD can be hovering around the mean or be very spread out for a highly diverse standard cohort.

Hi!
My son has been exempted from Mother Tongue (MT), hence the exam score will not be included, afaik.
In this regard, how to calculate TScore if kid is exempted from MT?
Many thanks for reply.
