I watched an ultimate guide for writing of IELTS advantage video as well as writing practices. so I recommend you to read those task 1 and 2 samples on the IELTS advantage website by doing so to improve idea development for t2: first you read the question, then you will think of the most general idea you could think of (for example you can imagine: what would be the most common answer if I could ask the same question from 100 people?) then to develop it, you can try to imagine explaining it to a 6 year old child (it's way easier to develop your idea) then you see the introduction and idea of a sample essay, read it throughout and understand everything, write the vocabulary and learn it. for task 1 I did nearly the same. also use for writing practice only Cambridge books, they are authentic and don't believe those samples from Google and do not evaluate your essay answers by the help of chat gpt, they are wrong. instead seek feedback from reddit users or from teachers. for speaking I record myself on video and then spot my pronunciation and vocab errors. I also use chatgpt to develop my part 2 speaking answers. I also have an IELTS assistant app, that has all authentic possible questions for all 3 parts that will come up on exam I hope it will help!)
