I didn't know it was impossible.. and I did it :-) - No sabia que era imposible.. y lo hice :-)

If helping your students write papers is a part of your school day, you probably already know that there are enough issues to focus on without having to spend a lot of time teaching your students how to build a bibliography and correctly cite their sources. Your time is likely better spent helping create a focused, concise piece of work that uses excellent grammar and sentence structure.
