The guide
Computer science
Computer Science
The study of what can be computed, and how: algorithms, data, languages and machines. It isn't training in any particular programming tool.
This suits you if…
You are willing to be a beginner at mathematics again for a year. You already build things nobody asked you to build. You would rather understand why a method works than collect a list of tools that happen to work today.
Look elsewhere if…
You want to make software and have no appetite for the theory underneath it. Software engineering and information systems degrees reach the same jobs with far less proof-writing. In several of the countries we profile, they are also the more direct route into a first role.
What this subject actually is
You will also see it called
Informatics · Computing · CS · Applied mathematics and informaticsThe same subject, under a different department in a different country. Search for all of them.
What the first year is really made of
Discrete mathematics, proofs, and one or two programming languages taught from the ground up. It's the mathematics, not the programming, that thins the year out. Most people arrive already able to write code, then find the course isn't about writing code. The ones who leave usually leave for one reason. Nobody warned them that a term of induction proofs and asymptotic analysis comes before anything that looks like an app.
The catch
The gap between the degree and the job is wider here than in almost any other subject. A graduate who never built anything outside coursework competes badly against one who did. The course doesn't require you to build anything outside coursework. So the work of becoming employable happens in your own time, alongside the degree, and nobody makes you do it.
The one hard requirement
Strong mathematics isn't optional here. Every country we profile screens on it, and the first year assumes it.

Kinds of work this opens
A list, not a prediction. Most people in these jobs did not study exactly this, and most people who study this end up doing something the list does not name.
