I think it's quite useful. I can cover listening, speaking, reading and writing, but of course it is almost impossible to improve IELTS scores just by watching and not practicing.

I used IELTS brother twice when preparing for IELTS, but I did it with Jane 9- 12. I usually do intensive reading by listening and reading in the IELTS exercise part after finishing Jane Eyre's questions, that is, I look at the wrong questions in the original text again and accumulate new words in the article (you can skip this step if you have too little review time).

Speaking English, I personally think it is the most brilliant section in IELTS. I usually use word to integrate all the quarterly question banks compiled by IELTS, p 1 and P2&; P3 is thus well segmented. Write down the key words of the content to be answered under each question, memorize them repeatedly and practice them repeatedly. I usually record oral English on IELTS, and I will also listen to other candidates' answers and add some different ideas to answer questions. After practice, mock exam training must be carried out, which is a relatively missing part of IELTS. You can speak fluently in IELTS or go to Taobao to find a foreign teacher to buy this service.

When writing, I will compare the real questions with the model essays given by IELTS brother, and I will also grade and modify the writing teachers online. I have read the model essay of IELTS brother's 88 composition and added a lot of arguments.

Generally speaking, IELTS is still useful for an online education tool APP, and you can see obvious results.
