First year we had 3 smaller essays (first one was on the ability to dumb down information and put it in the form of a news article - a largely stupid exercise I feel was just used to kick-start you into work if you were still living like it was freshers' week, second one was a critical appraisal of an article they supplied, third one was a literature review). They weren't very long and other than the first, the last two were relatively useful because if you're so research inclined then that's stuff you'll be writing. The large project is a 5000 word case study on a pregnant woman, which is very clinical and took quite a lot of effort to arrange the study, plan the interviews, etc.
Second year we had 2 large projects, a 5000 word case study again but this time on a patient with a chronic illness and then our first SSC which was a 5000 word literature review on whatever we wanted.
That's it really for us. Later on in the course, you have to do an audit which needs writing up, an elective report and some kind of case study of an ethical scenario you've experienced.
