Informatics 2A: Course Schedule and Lecture Slides, Autumn 2018

Lectures will take place at the following times and places:

Links to the lecture slides will become live at the time of the lecture in question. Should you wish to look at the material in advance of the lecture, feel free to look at last year's slides. These are not guaranteed to be identical to this year's slides, but in practice the content will be mostly the same.
