I’ve been putting together this website to help staff and students quickly find useful code snippets in VB.NET, Python or pseudocode (for GCSE Computer Science with OCR, AQA, Edexcel or Eduqas)

It aims to be a pseudocode, Python, VB.NET quick reference guide so you can quickly find definitions of key terms, a simple explanation of how key programming concepts work alongside code snippets that you can adapt and re-use as you learn.

VB.NET and Python are both programming languages designed to be understood and followed by computers. Pseudocode is not a programming language: it’s written to be understood by humans so that they can turn it into any programming language.

Each exam board has published a document saying how they’ll use pseudocode to describe algorithms in their exams. The whole idea of syntax (a set of rules) for pseudocode is silly - it’s not designed to be a programming language that is run by a computer. With this in mind, all exam boards state that you don’t have to follow the syntax for ‘their’ version of pseudocode when you write out your own algorithms, but you should be able to understand their version of pseudocode when reading an algorithm in an exam.

The idea is to give a really quick at-a-glance guide to explain some of the key concepts of programming that you need for GCSE Computer Science, alongside code snippets in Python and / or VB.NET as well as pseudocode for whichever exam board your school is using.

This searchable reference guide is designed for teachers and students preparing either for a Non-Examined-Assessment (NEA) or revising for a theory exam.

Please note:

Students are not allowed to access the Internet and are not allowed to have access to code snippets matched to pseudocode like this during their actual NEA sessions. This resource is designed for students to access for support outside of those NEA sessions.

Code snippets are split into 8 categories:

I hope they’re useful. Leave a comment below if you spot a mistake or think of something that’s missing that you’d find useful.
