The Archimedeans maintains a few (hopefully) annual publications.
Years of experience and knowledge have been passed down and compressed into this, the Holy Grail of guidance for Freshers, available as a PDF. This guide is produced by the Archimedeans and sent to all the first years before they come to Cambridge. If you feel that there needs to be some changes to what is said, please inform us so that we ensure the freshers are as well informed as they can be.
We collate some online lecture notes into one convenient location. The usual disclaimers apply — lecture notes are not a substitution for going to lectures, and many courses have changed since the lecture notes were produced, and the way material is presented varies with lecturer. Therefore, you should still go to lectures.
