One of the main differences between a Band 7+ candidate and a lower-level candidate is the ability to use a range of grammatical structures. Lower-level candidates tend to repeat the same simple tenses all the time (e.g. present simple, present continuous, will + infinitive) and they often use them incorrectly.
If your target band is Band 7 or higher, it is important to listen to the questions carefully and be prepared to use different structures in your answers.
If you want to improve your grammar for the test, it helps to become familiar with the different kinds of ‘grammatical’ questions and know how to answer them, for example:
|Type of question

|adverbs/phrases of frequency
|would + infinitive / second conditional
