22. How to Write?
• You select a topic and visit multiple websites again and again for this topic.
• Read at least 5 related websites, magazines, newspapers and social media to get
the detail information and write yourself. Do not write unnecessary introduction of
the topic, jump to the topic.
• Assignment should be between 400-600 words or more but not less than it,
multiple paragraphs, heading and sub-heading. Please do not put your personal
links inside assignment. Always submit with your photos and a short biography
(check one assignment: http://computingcage.com/why-microsoft-provides-windows10-for-free/).
• Once you complete assignment, do Spelling & Grammar check and check
Plagiarism Checker online. Upload a screen shot of Plagiarism results in the
assignment.
• Photos are beauty of any document. I suggest photos with white background, non-
copyrighted (a company name or logo should not be over photo) and bright. 22
