To be here long work, I think I should put their level of increase, so, I find no matter what kind of work will be better, then I heard a colleague that can let me take the Diploma in teaching Singapore, he said now the Diploma in teaching Singapore certificate exam is very good, but if you have the Diploma in teaching Singapore, when the job is really easy, hear what they say, I think, since that is the case, then I will go to the Diploma in teaching Singapore test anyway, as long as they are able to improve myself, I feel I should try.
