There is a course specification for every undergraduate and taught Master's course. Each course specification sets out the aims of the course, the skills and knowledge a graduate from that course will possess, and how it is taught and assessed.
You can find out what the course aims and learning outcomes are for English degrees at Warwick by using Search for Course Specifications. This information may be useful to you as a student because it will help you to understand what expectations your tutors have of your learning over the years you are at Warwick. If you need to clarify anything you don't understand in these criteria, ask your personal tutor to talk you through them.
