As an IELTS candidate, I found IELTS Playbook incredibly helpful for improving my essay writing skills. It provides simple, practical tips that really make a difference. The book walks you through how to understand the question, plan your ideas, and structure your essay clearly. It also shares useful "secrets" that help you avoid common mistakes. I really appreciated how it focused on what examiners are looking for. If you're aiming for a higher score in Writing Task 2, this book is a must-have!
