Any advice on how many listings is appropriate for the following experience? Let's say I volunteered for a summer to shadow a physician, and also did a research project with the doc. Then I presented a poster at a conference, and then some months later published the paper in a journal. List it 3 times one as volunteer, poster, and publication? Or just once? Problem is that if I list it only once, the full citation of the work takes up almost all of the 500 characters so there is no room to describe anything else.
