What you can do is find articles that cover topics that interest you. Read them and work with them. For example, you can paraphrase parts of the articles, you can read the articles aloud and record your voice to memorize the text even better, you can share parts of the article that you particularly like here in the forum, etc.
Try to focus on what really interests you. Don’t focus on IELTS because it’s an outdated, hierarchical system that has no future. Remember that you can only learn if you enjoy what you are doing, if you are really passionate about the activities you are engaged in. Please don’t tell me that you are enthusiastic about IELTS
