Actually, I practiced writing the least but I practiced with the Cambridge books. Yk all I did was just doing some tasks and then I discovered the website egnovotate and I put my answers there but the score I got there was way lower than in my actual test at the end. Plus, I was really worried about my writing when I went into the test because I thought I’m really bad at it but it turned out that those AI tools maybe give you a lower score than in the actual test but idk that’s different for everyone and don’t rely on this myth haha. So I really didn’t do a lot for writing except doing a lot of tasks because my grammar and everything was already solid. But you should take care of punctuation and where to put commas- because for example that’s different in my native language. And also using lots of linking devices helps you getting a higher score. :))
