Every piece of graded work in the course, what it is worth, and when it is due.

Three pieces of work. The first two are mechanisms you build, use for a fortnight and then demonstrate live in the lecture slot — nothing is handed in for either. The third is thirty hours spent on a subject you have already failed to get through, and an exam we set on the part of it you chose.

Both mechanisms can be built on paper or in code, and the two routes are marked identically. A paper system in daily use marks better than a half-finished program, and the reverse is also true.
