In Britain, one-year master's courses are usually conducted in a compact form, but whether it is necessary to write a graduation thesis depends on the specific courses and schools. Some one-year master's programs may require students to complete graduation thesis, while others may adopt other forms of research projects, internships or exams.

For a one-year master's degree, the graduation thesis is usually short, and the length may be between 10000-20000 words, but the specific requirements will vary according to different schools and courses.

Before choosing a course, it is recommended to read the detailed description of each course carefully, including graduation requirements and evaluation methods. You can also contact the Admissions Office or relevant academic departments for specific information on graduation requirements. Some schools may clearly indicate whether there are graduation thesis requirements in the course information.

If you have decided on a specific one-year master's program, it is recommended to contact your tutor or related professor before entering the school to obtain more detailed and specific graduation requirements information.
