Hello dear,
From the post alone i can see your english grammar and sentence structure is not nearly native. Maybe you think of eng as a subject and not as a language. Vocabulary does not prove anyone's calibre, as for the article published, I'm sure there must be an editor and proofreader to polish and carve out the final article after omissions of structural or other. Being a native English writer and speaker is very important because all you have to face in practical life is papers written in English as sadly after Arabic it has now become the leaders of the worlds' language. Esp. if FSP was ur frst choice its very very imp to shortlist candidates who can represent their country in a top-notch way and being 100% in four language skills is emphatic if you want to call yourself cream of the nation. Regards
