Each year, you have 4 papers (modules) that you study all throughout all three terms. In first year, you have no choice as everyone is coming in from very different exposure to linguistics as there is no A Level for it. The first year aims to give a solid foundation and touches on most areas of linguistics at some point. Throughout first year, you will write about 4 1500-word essays each term supplemented with worksheets. The linguistics department has their own guide to writing essays. The writing style is generally on the more factual, straight-forward side; it is more important to build a solid, evidence-led argument than to use fancy words. The worksheets vary in content from analysing a specific psychological study to doing a deep-dive into the structure of some given sentences. In second and third year, you get given a long list of papers you can choose from. Some of these are offered by the linguistics department and others are papers from other courses (e.g., MML, Classics, ASNaC, AMES). In second year, you can pick any 4 of these papers you want. In third year, you pick 2 remaining papers from the same list - your other options for third year are a dissertation and a broad paper on linguistic theory. Unlike first year, both second and third year ultimately count towards your final grade (weighted 30-70% respectively). In second year, you are expected to write around 9 and 16 essays for Michaelmas and Lent term, respectively. This depends on what papers you do as papers from other departments are likely to work different. Also, generally you have less worksheets but this is also dependent on your papers. Many papers also have practical sessions; these are sometimes baked into lectures. The workload for third year is similar but with fewer supervision essays to allow time for dissertation writing. From personal experience, the essays you will have to write can again be very varied: I've written about DeepFake algorithms the same week I had to read through rhyme schemes in the Qur'an. The course, especially in second and third year, is really what you make of it.

In first year, everybody studies the same 4 modules (Sounds and Words, Structures and Meanings, Language, Brain and Society and History and Varieties of English). The work tends to be a mix of essays and problem sheets. In second and third year, you pick from a selection of different modules. This can even include borrowing papers from Modern Languages or Classics.
