We list the exact number of words and approximate page count on all pages.
The 3 downloadable files (printer friendly, PDF, and Word) do not each have the same page length as our stated approximate length on the study guide, which is why we give the exact number of words, but no absolute number of pages. We provide the approximate length as an estimate to help you have an idea of the content length.
This is done because we condense the line spacing and use a smaller font on each of the files, but on the printer friendly and Word files in particular so that they take up fewer pages, less ink, and use less paper to print.
But, it's the exact same text. Please note that the PDF tends to have the full number of pages that is claimed on the website and is also printable. We just offer the printable format option in order to take up less paper.
