simple.
since you got ur diploma find a job that requires ur diploma,
compare to other job, u are pay more for ur profession.
meanwhile, apply for SIM, NTU, NUS, see whether they wan u or
not. Anyway, there is at least a 1/2 year lag phase before they
confirmed and enrolled u. Whack everything. It is they choose u,
not ur choice, unless, u have really good result.
if u r interested in whatever, just whack also. No need to think
so hard. After they say you are wanted, then you pick apples that
is already in your hands.
Going overseas, is good idea, but you need $$$. So u also need
to work FIRST to save enough. And they took like 1 years lag phase
before you get enrolled. And Whack every Uni. because they may not
wan u.
