The ranking don't mean anything if your son/daughter is not super intelligent type. The teachers there are not really very helpful afterall.
Their rise in ranking is most probably because they take in many foreign students, most of them are on our government scholarship. Most of these foreign students are from China and they are very hardworking and produce good A level results.
RI, HC and ACS have many China students but there is not many in Dunman high.

That's right. Teachers in RI and RJC are not exceptionally good. In fact, many of them are very bad.
