Comp Sci/Eng ususally are popular with JC students compare to
EEE/Mech Eng side, coupled with u got to compete with the top poly
grads armed with Merit/Medals or at very least a couple of
distinctions that make them above average. So chances are quite low
actually.
Part-time courses are usually the same course as the full-time
except they take a 5 years route (Such as the NTU B.Eng EEE/Mech
degrees both full-time and part-time take exactly the same
contents, exam and certification 1st/2nd class honours). Depends on
course availability (Such as NTU, I think they only offer EEE/Mech
for part-timers only)
Or the course itself to tailored to part-timers such as the
B.Tech courses in NUS (some-say is a watered-down version of the
B.Sc/B.Eng courses which I dunno how true is this).
From what I know, for getting a deg some where else then getting
into NTU, the success cases are ususally for post-grad where they
have a degree and come back to do their Masters. Then again, even
at post-grad level, the quality of your degree becomes important
(where/how/duration u get it). For undergrad, for my view, it can
be even counter-productive as in why let you in when u already have
a degree, etc, etc.
