Some people think their knowledge of English is reflected by the result they achieve at a language exam. Well, it can be true when they are familiar with the types of tasks in the exam, and they have their own strategies to solve those – in other words, they have their routine in performing well.
Without thorough preparation, anyone can face unpleasant surprises at the exam and receive disappointing test results.
Efficient preparation and useful feedback, however, will lead to achieving better results at the exam than relying simply on your knowledge of English.
