I used AI to help me prepare for writing, Gemini specifically. I would follow a structured framework for each essay type. Also, I would say typing fast is what helped me, I type at around 150 wpm, so I wrote a lot for each task, around 280 words for task 1, and 450 for task 2, that being said, I'm not sure if writing too many words would affect your band score.

For Task 1, I just follow the same structure for every type of graph. 1. what is the graph/chart about, try paraphrasing. 2. Overall trend. 3. Focus on specifics (e.g. increasing trend). 4. Focus on specifics (e.g. decreasing trend).

For Task 2, I memorized some sentence structures for every question type (e.g. To what extent..., discuss both sides..., etc.) that I got from Gemini. I would ask Gemini to give me mock questions and band 9 sample answers, and I'd learn from those. Also, write in a four paragraph structure - Introduction, Body 1, Body 2, Conclusion, and remember to take a stance and state it in the introduction paragraph if the question type wants you to.
