The 2017 version of the course was run via Moodle but here is some static information.
Below are all the past exams for the unit, together with the comments supplied by the 2015-16 lecturer (not me) for most of them, explaining how the conventions and coverage differed from what happened in that year. Since I used his notes when I lectured the unit is 2017-18, his comments are still applicable and no further comments on the 2015-16 or 2017-18 exams are necessary.
The Unit Catalogue entry gives a brief summary of the content of the course.
The principal recommended book for the course is M. Reid, Undergraduate Algebraic Geometry.
There is a handout about the Nullstellensatz, available in ps or dvi or pdf.Last modified 1st Febuary 2018.
