Hi there! Allow me to add in a couple of personal opinions.
Firstly, a brief intro, I was a former graduate from Temasek poly,
in Visual Communication. Currently doing part time studies in
Communication and media in University of South Australia (long
distant learning) in Singapore. Working in a branding department
here.
I would not be able to throw you enough details on TP. Like other
polys in Singapore, it offers a wide variety of courses, ranging
from engineering, business, IT, and of course, design where i
graduate from. To get a better picture, you should visit the TP
site at www.tp.edu.sg
That should bring you through a quick overview of what TP offers. I
suggest you make a trip down to the school, collect some brochures
and speak to people in charge there.
If you are doing a full time course in any local schools here, i
don't think you have time to do any work, maybe some part-time or
weekend jobs.
Have you considered any other schools, beside NUS. How about NTU?
What are the reasons for them to reject your application?
Alternatively, you can always take a degree course in Singapore
(long dist. learning) from any other countries. You can try SIM.

I am not a career counsellor, so I won't be able to tell whether or
not you can find a job upon graduation. There are many factors
leading to the answer of that question. Your results, your
attitude, your experiences, etc etc. If you are not fussy, it's not
difficult finding a job here. If you are willing to learn and pick
up things fast, there are always doors open for fresh
graduates.
So, hope my few opinions helped!
good luck to you!
