Department of Computer Science and Technology


Exam format for June 2023

The structure of the exam papers will be very similar to those used in previous years and is available here.

The examination timetable is now published on the dates of the tripos exams web page.

Papers for Part 1A and Part 1B will be in-person, closed book, duration 3 hours. Part 1A NST Maths papers will also be in-person, closed book*.  Please refer to the University Guide to in-person exams.

*1A Maths exams are run by the Natural Science Department and the code of conduct will be different this year from your Computer Science exams. The two Maths papers will be closed-book and in-person.  Link to the NST Mathematics Course website for past papers etc.  Note: Calculators are not allowed for these papers.

Slides from the 1A Examination Briefing on 24 May 2023 can be found here.

Papers for Part II will be online, open book, duration 3 hours with additional time for uploading answers.  Please refer to the University Guide to online exams in Moodle, and the Department Guidance for Part II Online exams 2023.

Form and Conduct instructions

  • All CST Examination papers last 3 hours.
  • You should have received notification if you are allowed extra time for your examinations.
  • For each paper you answer 5 questions. (Note: Students are strongly advised to only answer five questions, as only five will be marked and there is no guarantee this will be the best five. The examiners may simply mark the first five that they receive, so submitting more than that gives no advantage.  Students are advised to concentrate on providing five good answers rather than spreading themselves too thinly by answering more than are needed.)


The current guidance regarding plagiarism and academic misconduct still applies and is given here. However, for the open book examinations this year, it is permissible for you to quote from your own previous work directly without attribution. In addition, you may also use material from lecture notes without attribution.

Computer Science Tripos Honour Code

  1. We take it as a principle that maintaining the integrity and fairness of examinations should be regarded as a collaboration between students and the Department.
  2. The students undertake that they will not help others in examinations and will not receive any help from others (students or non-students).
  3. Students will actively contribute to ensuring that all students adhere to the code.
  4. Students will keep to the conditions of the assessment and will accurately report those conditions where asked.
  5. The Department will not make any attempt at remote invigilation of online examinations.

Further information regarding Honour Codes

An honour code is a mutual agreement on academic integrity by students and faculty. For example, Stanford’s honour code is set out here.

Note the emphasis on mutuality: Stanford takes the principle of trust very seriously and does not invigilate (`proctor’) exams in any way. Indeed faculty are not allowed in the examination room.  Since, unlike Stanford, we do not have 100 years of tradition of an honour code to fall back on, we recognise that there may be people who have suspicions about integrity in online examinations. The examiners will therefore conduct vivas as necessary to ensure the integrity of the process.
