I was so frustrated sitting at 6.5 for my IELTS writing! After a couple of tests, I realized that the key wasn't about using fancy words but actually simplifying my writing. I focused on structuring my Task 2 essays better.
Here’s what worked for me: I made sure each paragraph had only one clear idea. Starting with a strong topic sentence followed by a specific example made a world of difference. And I stopped adding new ideas in the conclusion—just a summary of what I already said!
