NST/CST Part 1A Mathematics Past Exam Questions

This document last updated: 27 December 2023.

These pages provide comments on past exam papers for the Natural Sciences/Computer Sciences Part 1A Mathematics Course. Where there is no comment for a question, it probably means I've not yet had a go at it. An asterisk (*) denotes particularly good questions to try.

NB: the question numbering for Section B of the 2008 papers differed between the paper actually sat in the examination hall and the version now online. The paper sat in the examination hall had questions starting at B1, whereas the version now online had questions numbered as below.

2006 Papers 1 and 2, 2008 Paper 1, 2010 Paper 1, 2016 Paper 1 and 2023 Paper 1 were hard overall. Don't start with any of these when revising! 2012 Paper 2 was relatively easy.
