Computer Science courses
The computer science courses listed here are the academic core rather than the tooling: algorithms, data structures, computer architecture, operating systems, theory of computation and the maths underneath. The providers include Harvard University, Stanford University, Peking University and UC San Diego.
This is the subject to pick if you are filling gaps a bootcamp left, or preparing for interviews that test fundamentals rather than frameworks. If you want to ship a product instead, Programming and Web Development are the closer fit.
A Computer Science course is worth paying for when it closes a gap someone is hiring for. Read your CV against the job you are targeting in CV and Job Match, check what the role pays and who is advertising for it in Job Scout and on the salary pages, and let Course Path put the remaining gaps in order, cheapest and shortest first where that makes no difference to the outcome.
Computer Science courses worth starting with
The catalogue holds 249 Computer Science courses. These 15 are the ones we point people at first, chosen for a provider name a recruiter recognises, a credential worth writing on a CV and a description that says more than the course title. Each page carries the provider, the level, the length and the certificate. The rest of the subject is on the same page, and the filters search all of it.

What this page lists for Computer Science
249 Computer Science courses have a page on this site. By platform that is edX 150, Udemy 54, Coursera 41, Scrimba 3, DataCamp 1. By the level the provider states, 72 beginner, 156 intermediate, 21 advanced. On credentials, 2 are a Professional Certificate and 247 a plain certificate of completion. Every one of those counts is a count of rows in the catalogue on this page, and every one of them can be checked against the filters on this page: set the platform or the level and compare the number of results.
What this page does not cover
- 150 of the 249 come from edX alone, so this shelf reflects what edX publishes more than it reflects the subject.
- We have not taken these courses. The level, the length and the certificate line come from the provider's own listing, and nothing on this page is a review of the teaching.
- A certificate is usually a paid extra rather than part of a free course. edX states of its own audit track that "Auditors have temporary access to edX course materials at no cost", and the certificate sits on the paid track instead. Read the price line on the course page before you assume a free course ends in a credential.
- Careery earns affiliate commission on some course links. It does not change the order of this list, which is set by the filters you choose, and it is the reason to say so here.
- This is what we list, not what exists. A subject missing from the counts above is missing from our catalogue, which is not evidence that nobody teaches it.
