We often see PTO words printed on exam papers, books journal, newspaper magazines, etc. Therefore, the term PTO is a reference to "Please Turn Around" (or page turn over that is a direct translation of "Please turn the page" and move to the next page. This means that the person writing is trying to inform you that the information will be available at the end of each page., and they should take a look. Another reason to use this technique is when you write an answer, letter or something else and it was not completed in one page , so you had to write your thoughts on the next page. You can also make a small PTO on the lower right of the page to convey your reader. When you do this it is certain that the reader will be able to see the page when they turn the page.
