If I get a proverb in the writing section 2. shall I rephrase the proverb? I saw this in proverb question in opinion essay question section on your website.
I would also recommend avoiding proverbs as well. Most proverbs are not appropriate for academic writing. Here’s an example of an inappropriate proverb in writing “all that glitters is not gold”. While the meaning might be perfect for your essay, it would be better to write “people should not be deceived by appearances because they can be deceptive” The latter sentence has a much better variety of appropriate vocabulary for a high score.

It is not possible to learn sentences and put them into your essay. The examiner is trained to spot learned phrases and they will not be accepted. To get band score 6, you must have band score 6 English. This is ultimately a language test, you must have the level of English suitable to the score you want to achieve. My recommendation is to improve your level of English so you can write complex sentences without too many errors. Learn ideas to apply but not fixed sentences.
All the best
