In recent years, around 60% of GHPS students can be promoted to GHS. Another 10% students will go to other Band 1A schools like DGS and MCS. Hence, the Band 1A % is about 70%.
For SFA, the % allocation to Band 1A schools is similar if you include HTC. For the remaining Band 1C / 2A students, SSP has better schools like Our Lady of Rosary and Tak Nga than WTS.
