I am an undergrad preparing my resume for grad school application. During my undergrad I have done many projects, including a few real research projects and also those for courses as final projects, that were just about designing something rather routine (a simple robot for example), or a compilation of other research works. Most of these class projects have had a report (a writing).
Since I have just one official peer reviewed conference paper, is it a good idea to list all those technical reports in my resume in the Publications section? Or, conversely, adding these may decrease the value of that peer reviewed paper and making the resume look unprofessional?
