I used to teach tutorials at Keble college (Oxford). Not sure how they were run in Manchester.

Tutorials in Oxford are impressive for me for many reasons: 1. Those teaching were generally of a higher level beyond Ph.D., post docs or professors, all paid, all assessed against an NPS from students, and the performance of the students in exams 2. Tutors are generally teaching more adjacent topics (creating connections), students are challenged to think beyond the assignments (which are generally tough), 3. Tutorials are calibrated and personalised to students and made sure all students are challenged at the right level, I had tutorials where I had to teach 1:2 because the students were excellent and needed a higher level of complexity.
