A first-class honours degree in the UK typically requires an average mark of 70% or above across all exams, with the final year often weighted more heavily. Approximately 10% of students may achieve this classification, although this can vary based on the difficulty of exams, as grades may be adjusted if the overall performance is too high or too low. For students outside the UK, the same grading standards apply at UK institutions, but there is no standardized method for converting foreign qualifications to UK equivalents. Prospective graduate students from abroad are advised to contact admissions tutors for specific guidance on their qualifications. The classification system can differ by university and subject, with some institutions having higher thresholds for first-class honours.
