My advise is if can.. best is to study in local polytechnics.
Start from ITE then slowly advance into Polytechnic if you don't
plan to take 'O' Levels to advance into Polytechnics. Don't waste
your time and money on some private diploma certs that is not
recognised. And some private companies' employers have the mindset
that private certs are very commercialised, and require only very
short time to complete the modules.
By the way, I heard if want to work in a Government Ministry or
etc, most private diploma certs will not be recognised by them? Is
it true?
