Ah Jun,
You can try SIM/MDIS certificate level for O level holders.
Once you have the certificate you can proceed to do their
diploma level courses.. and subsequently.. you can go for degree if
you obtained good results.
They will give you bridging class and examination if you do not
have your O maths to justify entry.
But if I am not wrong.. they have a minimum age requirement and
some amount of working experience.
I suggest you go down to the customer service counter and speak
to the customer service .. bring along all your certifications.
Both institution runs part-time and full time course. So it
depends on your financial ability too.. If your parents cannot
afford it.. you can always work full time and study part-time, this
way.. you get your cert AND clock your working experience. Tho.. it
will mean discipline and hard work and plenty of sacrifice on your
part.. can you do it ?
