Should I turn in partial work or wait until I am done?
Most of the weekly course modules ask you do a number of concrete activities that help you build toward your final portfolio. These may include making a single webpage or posting some feedback to fellow students. We try to be very explicit with what will be getting graded in each module.
The Flipgrid assignments, while important, are ultimately less than a third of your overall grade in the course (see the syllabus for the full grading breakdown). Even then, the emphasis there in not on the quality of your portfolio work, (the style of your resumé, for example) nor its completeness. That will happen later—at mid-semester feedback, final exhibitions, and final feedback. Instead, we focus on whether you posted a link, and made some good faith effort on the assignment by the deadline and are able to report that.
In summary, we believe it is better to get something for a assignment posted on time (like a draft of a resumé) and to improve upon it as we go than to wait for everything to be perfect. There will be time to revise and improve later.
