Writing is one of the most important skills English as a second language learners must master, particularly for students and working professionals. That’s because unlike in speaking exercises, when you write you leave a lasting record of your language.
Mistakes in spelling, grammar and word choice are immediately evident. And while literacy skills are not a reflection of intelligence or knowledge, poor writing can cause a student to receive lower marks, even if they know a lot about the subject of the assignment. In a professional context, people may judge you as lazy or untrustworthy if you send poorly written emails full of mistakes.
They are also likely to assume your spoken ability in English is quite low, though this may or may not be the case. That’s why it is important to improve writing skills in English before they prevent you from reaching your full potential at school or in the workplace.
