One online posting short essay，need before Nov 9th ，3PM

ON-LINE POSTINGS:  Three on-line postings, submitted to the relevant Exam Period module of the class Canvas site — one per exam period – count toward your final point total.  Each posting is worth up to 15 points.  Your lowest posting score is dropped, so you can submit a post during all four exam periods, but again only three will count toward your final grade. If you earned perfect scores on your first three submitted during the first three exam periods, you do not need to submit a post during the last exam period.  Two postings for a grade cannot be submitted during the same exam period. Postings are due Friday at 5 pm at the end of the exam period, with the exception of the posting for the last exam period which must be submitted no later than 5 PM on Friday, November 30 (NOT the last day of class).  Students may submit non-graded postings to the discussion forums, but only students’ first posting during a given exam period will be graded (editing a post after it is submitted is not permitted, so make sure it looks good before submitting). Remember to keep a copy of your post before you submit it as a backup.
