Interesting how these things go in cycles. When I sat for my first degree, in the late 1990s, it was all assessed on seven papers, written in 3 hour exams, over the space of ten days. Your Dissertation was submitted earlier in the year, which you got to do yourself, in your own time. At the time, it was absolutely awful.
There was a move to 'split finals' (across 3rd & 4th year - I'm in Scotland) in the early 2000s, which spread the load. Then, further to a mix of assessments - so essays, exams. presentations, projects, etc. When I undertook my MSc in the mid-2000s (in Australia, not UK), the model was based on this form of assessments. This was to give the best opportunities to all students, as it's recognised that not everyone learns in the same way, or performs best in the same way.
Funny how we're musing moving back towards that 'write all your papers in exam conditions', to avoid this, instead of using a range of assessments which are designed to be very difficult to use AI or essay mills for.
