If you've got good friends that are around the same ranks as you, (me and my group were usually top 10 at most subjects, big cohort) you can share your assignments around as long as they share them as well. But this obviously becomes risky as you guys might take some concepts and mash them together and you might create similar pieces. However most of the time we would be like "how did you start your intro" etc. and sometimes we would help edit their assignments to help add another perspective.
