if i am not wrong,
the particular course that the TS is going through is an enrichment
meant for normal (acad) and normal (tech) course to give them an
idea of ITE-related/vocational training courses. It is usually
something like video game design, retailing, hair dressing,
motorcycle maintenence, video editing, web-design and the
like.
the money comes straight from MOE specifically for students of
these two streams. The school can only use the money for this
purpose, but it is up to the school to choose the course and the
vendor.
If i am not wong, i believe it is held on a schoolday, so there is
no reason to skip it.
There is definately something to learn.
