What undergraduate work stays on a CV once you start graduate school? I'm about to graduate with my BS and I'm trying to decide whether it's worth it to submit a paper for publication in an undergraduate journal, given that I've already applied to and picked a PhD program and I start on the fall.

What sorts of papers, presentations, and awards that I received as an undergrad are still worth mentioning on a CV even after I graduate? Do my accomplishments restart like they did after graduating high school?
If you are considering writing and publishing something in an undergraduate publication -- don't do it for the sheen it might add to your CV.  If you do it, do it because you find the subject matter interesting and you think you can write an article others would enjoy reading.

Note, the more you write, the better you get at writing.

(Separately, after publication, you could ask for guidance about what to include and what to exclude from your CV, if the existing Q&amp;As here have left this an open question.)
