I graduated from Durham with a BA in English Literature about two years ago (so was a student there from 2020 - 2023) and the English Literature course there would be a really good fit for her.
The assessment breakdown is such:
Year 1 - assessed 100% by end of year exams.
Year 2 - the two compulsory modules (Shakespeare + Literary Theory) are assessed 100% and 80% by end of year exams respectively. The majority of optional modules (including Victorian Literature + Literature of the Modern Period + Renaissance Literature, which will appeal to your daughter if she likes Classics) are assessed 100% by end of year exam.
Year 3 - it's compulsory to do a 12,000 word dissertation and four other modules. Of those four other modules, a maximum of three can be lecture modules (assessed 100% by end of year exams). The remaining one has to be a seminar module, which is assessed across two 3,000 word essays.
The exams take the format of 24 hour online open-book exams in which you write 3 essays of between 1,000 and 1,500 words (exact word count varies from year to year and module to module). I really liked this because (factoring in sleeping) it gives you 4-5 hours per essay; enough to get stuck into your arguments but not so long you can read + edit endlessly.
For each exam module, there's the opportunity to write a formative essay a term to get feedback from lecturers. Anecdotally, my friends and I found that if you wanted more feedback, lecturers were also very receptive to reading + marking practice essays you might have done in your spare time.
The reason it can be difficult to find out how the course is assessed is it can vary a lot within one degree programme depending on the module combinations you take. But to find out how individual modules are assessed,you might want to try searching for each university's module handbook - this is the link to the Durham one: https://apps.dur.ac.uk/faculty.handbook/2024/UG/department/English%20Studies. They're designed to help current students choose which modules they'd like to study, but they're also a good way for prospective students to get a flavour of the course. Where they're not available online, if you email the Head of Department at the university you're interested in, they're normally more than happy to send it across.
