The IELTS Writing module is widely regarded as the most challenging section of the exam. Unlike Reading and Listening, where answers are either right or wrong, Writing is subjectively assessed based on clearly defined band descriptors.
Many students struggle not because they lack English ability, but because they do not understand how examiners actually think while marking answers.

- What each band really means
