If you are starting the FDLT course in September you might like to read some advice from some of the students who have been on the course. You can find this above on the page called ‘Advice from students to applicants’.
You might also like to browse through the diary pages to get a sense of some of the activities students have participated in.
At the interview this book was recommended. Looking at the early chapters about preparing to study would be useful over the next few weeks. There is a companion website here.
