Thanks so much
Need more help on going postgrad?
The Faculty of English at Cambridge specifically notes: "In recent years the Faculty has admitted very few students for this degree. It is generally felt that many candidates would benefit more from a one-year, taught course such as an MPhil, or from a full three year period of research for the PhD".
If you're interested in postgrad research, I'd suggest looking at PhD programmes (at Cambridge or elsewhere). I'd note Cambridge normally expects you to have a masters before embarking on the PhD (which seems a common requirement for arts/humanities PhDs generally). While the masters courses are "taught", it's worth bearing in mind the format of assessment and structure of taught components are normally different between UG and PG students.
To wit, the masters courses in English at Cambridge are normally assessed by two extended essays (of around 5k words) and a dissertation (of 12-15k words), so you will be doing research and extended prose writing, similar to your dissertation, in the "taught" elements on the course.
