Assessment
Assessment for the course is as follows.
- five courseworks, five points each, including a take-home mock exam (the “mock mock”), 25%
- optional project, take a research paper and formalise its development, 25%
- mock exam, online with Agda proof assistant under exam conditions, 0%
- final exam, online with Agda proof assistant, 50%
Students are expected to get 3–5 points each (out of 5) on the courseworks. Students who undertake the coursework and mock exam typically get 50 points (out of 50) on the final exam. In order to conform with the University’s Common Marking Scheme, students may typically get only 10 points (out of 25) on the optional project. Attempting the optional project may not be a good use of time compared to other courses where there are easier marks to be had.

The optional project is to take a research paper and formalise all or part of it in Agda. I suggest formalising the paper here, but talk to me if you want to formalise something else. (A more recent draft of the same paper is here.)
