Department of Computer Science and Technology



Tripos Examinations will take place in early June 2021. All papers will be three-hour online examinations, but with additional time for uploading answers. The structure of the exam papers will be very similar to those used in previous years and is available online. Candidates who normally qualify for additional time in Examinations will continue to receive the same additional time.  

All Examinations will be open book, so you may refer to your course notes and other resources if you wish. You may not discuss your answers with anyone else during the Examination. We will ask all students to sign an Honour Code (see below). The Examiners may conduct online vivas with students after the exams have been completed.

Further information on how to prepare for open book exams 

Submitted exam answers will be marked and graded as normal.  Unlike last year, no examinations will be formative so students in all years will be classed.


The Examinations will be run centrally rather than by the Department. We expect the Examinations to run in a similar way to last year’s Part II Examinations, but the details have yet to be decided. We will update this page with further details as they become available.

There will be some sort of limit on the length of typewritten answers, possibly the same as last year’s limit of 4 pages, but this is yet to be determined. Handwritten answers will not have a page limit.

We will provide a separate FAQ page in response to queries if required.

Computer Science Tripos Honour Code

The Honour Code below is the one used in Easter Term 2020 and we expect it to remain substantially the same in 2021.

  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 on 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.
