I'm doing a small research project for an English undergrad class about the differences in psychology undergraduate and graduate school, in relation to writing. I'm a psych undergrad student right now and after researching a lot about different graduate schools, I don't feel as if my undergrad classes have prepared me enough for the co-authoring papers, writing dissertations, etc. that graduate school apparently entails. So, I'd really like to hear your opinions: are undergraduate psychology students prepared to write what is demanded of them in graduate school?? How is writing in grad school different or similar to writing in undergrad?
