If you got 7~10 points for ELR2B2*, it's almost guarantee you a
place in Polytechnic of any course which you like.
*ELR2B2 denotes English Language, 2 relevant subjects(Maths &
Sci), and 2 best subjects(any).
That means, the decision lies in you to chose a course which you
are interested in. Myths says that polytechnics is a slacking
heaven, but the actual fact is that if you want to do well, you
must put in a lot of effort.
If you got 7~10 points for L1B5, then you can get into to most JC.
The stellar results will enable you to have a more flexible subject
combination of your choice.
My opinion if I score 7~10 points, I will go chose to go
Polytechnic and chose the course which I like.
