Where can these lessons take you??? You can go anywhere from here. Many international students are required to take English tests and pass them as a means of demonstrating a certain level of proficiency.
How can you best prepare for an English test?
It is different from what you expect. In my experience many students can pass the tests but, they can't still communicate. it turns out that many students JUST prepare to pass TOEFL, IELTS TOEIC and other English tests but, lack to communicate with conficence and competence to function in their classrooms and in the society. They are just test takers but, they can not apply their language skills in real classroom situations.
With this in mind, perhaps one of the best ways for students to prepare for any English test is to actively engage in their regular classroom activities. Reading for pleasure, volunteering in the community, getting a job that requires interaction with others are all indirect ways of preparing for any test. Read preparation book to familiarize yourself with the test, but make sure you are
practicing your language skills in many different situations.
