Language classes have gone hi-tech. Translation: You can now learn languages online and in real time, like in a private tuition setting. Forget lessons in the classroom or listening to language tapes. That is so old English. Nowadays, there are online courses teaching just about any lingo you like, ranging from fee-based types to free. The demand for such online classes in Singapore is still in its infancy, but in terms of supply, a simple Google search throws up a wide range.
