Do not ignore the syllabus:
Failure to complete any requirement (including speaking in discussions and submitting evaluations) means failing the course.
Also note:
The discussion evaluation is a ONE-page exercise. Adjust spacing if necessary, but submit ONE page. Evaluations that run over into a second page–even if it is only a matter of spacing between sections–will not be read/credited.
Also, proofread. Eliminate the careless typos and the ungrammatical sentences.
