it is a single stream. so it is still stream.

also, i think it works like college where ppl may go for different classes that they are interested in and yet share the same class for basic subject like bm bi sejarah etc.
im curious how it will be handled and im pretty sure it wasn't "cause more segregation" as claimed by intellectual /k.
the abbreviation of the word STREAM is just to say it is a single stream that consist of all together.
