Increasing numbers of students are travelling abroad for study and so find themselves in the situation where in addition to acclimatizing themselves to a new country and taking on a full course load, they also have to consider whether to take English courses. For some there is just no way around it, without an English course there is no way they will be able to articulate well enough to pass.
Those of us who were lucky enough to be raised in multilingual homes will be the first to say that the experience is wonderful; it opens doors, it creates opportunity and it is simply a pleasure. Not everyone is as lucky but for them language courses can be the way to go. Sometimes it’s necessary not for pleasure but because English (or another language) is a second language in an adopted country and you simply won’t get by at work or school without some English language courses.
