Why article errors still block Band 8 writing

Recent lists of Korean learner mistakes highlight missing articles and dropped plurals as top issues that persist even with daily practice routines. In writing tasks aiming for 250 words, the wrong article changes meaning in ways that examiners notice under band descriptors for grammatical range. Correcting these patterns once reduces the same slips in job emails or contracts where clarification is not possible. It depends on context whether the omission sounds natural or simply inaccurate.
