CCKG, SC, SPK/SPN, LH, SKH, KV, Victoria, SSG
weird.. never heard of HKPS..
But, even with LH or KM .. those are because their sisters are already at DGJS. Lot of related points... but their major source of students are from CCKG, SC, SPK/SPN, SKH, KV, Victoria..
Don't think students from LH had great chance to dgs , even they had, maybe 1-2 , and not every year. The others you mentioned was correct, as far as I did research....
For LH to DGJS, they might have their own relationship like sibling or others. Rare too... as you say ... not many.. so is more safe with the big name kinders.. if you are targeting these schools.
But, KV to DGJS... for those got admission, their academic is strong in lower forms.
Pods is really good. I am reluctant to give up Pods. My kid loves to go to school and he shares his joy at school to me. He told me that is fun to go to Pods. At least, I feel bad to switch him out to KV. However, for better primary school foundation, I still prefer KV, no matter if my son can be trained to be one of the elite ones... I guess I need to try KV before I can tell he is fit into this school.
