In this field, take the responsibility of every action you made. The salary pay scale that mention in this forum is true. Do not expect much. In singapore, salary for lae is sucks. One day eventually those who impatient and not daring enough will find themselves stuck at the middle of nowhere in this career. The earliest time for you to earn big money is after you join the scheme for 7~8 years. (if you are lucky)
[The big money I mention is only sgd12k+ basic hour per month]

Quality for those who wish to join lae scheme.
1) Endure
2) Prepare to be sandwiched by technician and management.
3) Daring
4) No need to be well educated but need to have basic education and HIGH IQ.
5) Prepare to die early comparing to normal people. (toxic chemical)
6) Accept all the action that you have taken n do not regret. (accept so much responsibility for 2.5k ++?)
7) Able to handle stress.
8) Super fat ass not encouraged to join. [Unless u want to slim down]

Out of all the criteria if u still can't decide, below there will be one experiment for you.

1) Get a can of used engine oil that in black colour, pour it on to your toilet, include the lid n the bowl itself. Then go n wear a stupid coverall, squat down and clean it with dry rags by your hand. After you clean all the oil stain use a torchlight n mirror inspect the toilet see whether u satisfy with the cleaning.

[ I bet for sure you will have plenty of chances to encounter this kind of job if you become a member of the scheme. This experiment is the easiest way to test whether u r fit or not. Remember in the above test u just squat at the side of the toilet to do the job. In real life of lae, alot more shittier job awaited you, be prepared to stuck your head inside the bowl or crawl like a dog inside the compartment.]
