In my native language, we don't have too many rules for writing. Writing in my native language is not so strict with punctuation and grammar rules. For example, in English we have to follow all the rules in our writing like punctuation, period, etc., but in Farsi these rules are not so important. The main purpose of an article is to give the idea to the audience. In college English writing, besides giving the idea, the author should follow every rule, and this is why writing in English is difficult for any native speaker.
