Many students know very little about apostrophes and their writing really shows it. Quotation marks must be placed both at the beginning and at the end of the word or words you are using. Many students are forgetful with quotation marks. They often mark only one end of the quote, or do not mark the quote at all. Use it instead of a full stop.
Many students fail to mark questions.
Sometimes they do not even realise they have written a question until we point it out. You ask many more questions than you may at first realise. Otherwise, ask at your local library.
