If one of the training companies in singapore is really bad and unreliable, it will be easy to find information about it. People who are unhappy and have been disappointed with a training company will be quick to write up some reviews and post them in as many places as possible (usually online). That is one reason why you should always look whether you could find some third party information about one of the training companies in Singapore that you are interested in using for yourself or your company. One or two bad reviews do not have to mean that the company always sucks but if there’s dozens of bad reviews from different people, then that is a big warning signal. I would stay well clear of a training company that only seems to produce dissatisfied customers. You should always seek out places that have happy students (customers); after all you want good training.
