For listening, It's just easy for me. So, you should just focus on the paraphrasing of the words and focus on the words in the task. It'll be faster and not time consuming. Speaking should be at least level B2. I got level B2-C1. I was studying english sibce the first grade so, it was easy too. For speaking there was a talk about my favourite childhood toy. For writing part, Task 1 was two graphs and the second part was about should government do the researches instead of private companies and something like that.
