This Easter Term (2015) I am giving revision supervisions in several courses for several colleges. All students, please go to the CamTools site for supervision times (will be advertised in email to you all).
Groups Ia lecture course
In Michaelmas 2014 I lectured the Cambridge first year course on Groups. Here is the lecture-accompanying blog Think for yourself.
Lecture notes (last updated morning of 29 April, corrected several typos. Most important one: p. 28 Definition of normaliser: Clearly H is a subgroup of it's normaliser.)
Video solutions to some example sheet questions. You should only look at these once you've tried the question!
Some data will be saved when you watch the videos, such as where you pause, what answer you clicked, etc. You can use the tick boxes on the list of videos to indicated if you have "completed" a question; I will also be able to see this information.
