# Information theory and coding supervisions (2009–2010)

The course webpage contains links to the syllabus, past tripos questions, lecture notes and the learning guide.

Please make sure that your work reaches my inbox at least 24 hours before the supervision, either by email or paper-based via the post box outside Student Administration in the William Gates Building.
