if u r confident in doing better.. maybe u can try to retake as
a pte candidate, but i can say its quite hard to study while
serving NS... i know of a fren who did that.. and his retake
results wasn't any better than his previous one... after NS he just
packed his bags and left for an overseas college , start all over
again from pre college (= to sg's junior college) courses...hoping
to get a place in a uni over there....
another alternative , u can try taking up a recognised degree
course of your choice in sg, at some pte institutions like SIM or
MDIS... they dont have requirements which are as strigent as local
unis.. but being able to get in, doesn't guarantee u a cert in 3
years time... u still need to study real hard to get good grads or
even to graduate...
