Hi Bobo, first of all, i like to say that your comments are good and fair.
ignore that prick who only knows how to hurl rubbish without any facts to substantiate himself

But i managed to earn more than 5k in 4 years of working.
I am a 3rd class honours from NUS, mech engine.
Started off in a shipyard as an engineer with 2.4k per month.
Left the shipyard 3 years later at 2.8k per month.
Managed to get into a MNC at 5.1k per month.
So i say it is possible.
