text: Best Wishes or Best wishes? Yours Sincerely or Yours sincerely?
  In the IELTS General Training Module, you will need to write a letter.
  It is important that you correctly end your letter. A lot of people choose the correct closing salutation, but many capitalise BOTH closing words.
  When you’re finishing a letter (or e-mail) make sure you capitalise only the first one. This applies to formal and informal writing in both UK and US English. That means that the following are all written correctly:
  - Yours sincerely
  - Kind regards
  - Best regards
  - With love
  - With best wishes
  - Yours faithfully
  - Yours truly
  Note: if there is only one word in the close, then make sure you capitalise it. For example:
  Make sure you don't make this mistake on test day
