In Britain, the weight of master's thesis is usually quite large, but the specific distribution ratio will vary with schools, majors and courses. Generally speaking, the proportion of master's thesis can occupy a very important position in the whole master's course, usually between 40% and 60%, and sometimes even higher.

The following are some possible distribution ratios:

40%-50%: In some master's courses, the paper weight may be between 40% and 50%. This usually means that other forms of assessment, such as exams or course assignments, also account for a considerable proportion.

50%-60%: Thesis accounts for most of the scores of the whole master's course, which may be between 50% and 60%. In this case, other forms of assessment may be relatively rare.

60% or above: Some master's courses pay more attention to research and academic writing, so master's thesis may account for more than 60% of the whole course score.

The specific distribution ratio will vary according to the nature of disciplines and majors and the teaching philosophy of the school. It is important that at the beginning of the course, you should read the course manual or related documents carefully to understand the weight of master's thesis and the distribution of other evaluation forms. If in doubt, please consult your tutor or course director.
