Your turn! Student Projects

As per the syllabus, 5% of your grade will be based on contributing a Rhea page on a subject related to the course . To pick a subject, simply write your name next to it. Please no more than one student per subject. Your page will be graded based on content as well as interactions with other people (page views, comments/questions on the page, etc.). The number of links to other courses and subjects will also be taken into account: the more the merrier! Please do not simply copy the lecture notes and do not plagiarize. Read Rhea's copyright policy before proceeding.
