Oh... I see...
From where I come from, there is such a thing as well. Not sure about college selection but I know about secondary school selection. (or you would call it high school) You would have to do it online, and choose the schools you want to choose. You only have 6 choices. They would look at your PSLE grades (PSLE is the national exam for primary schools, or you would say elementary school) and most of them have a cut off point. The results are keep inside the government secret computers. So we don't need to sent them.
