OCR Reference Language J277 - Complete Crash Course For GCSE Computer Science

Welcome to the OCR Refence language crash course.
This video is aimed at students studying OCR computer science at GCSE and is for students to quickly learn enough of the basics to be comfortable with programming questions found in paper 2 in the OCR J277 Specifications.
Note: This is not meant to be a comprehensive guide but as the title implies a crash course to get you through the exam basics.
To make this guide more accessible all text is in a dyslexic friendly font (OpenDyslexic) also I am talking a bit slower to make the video easier to follow and recommend watching at x1.5.
With this out of the way, Happy Revising and Good Luck!

4 weeks away from exam and didn’t realise this language even existed. This is very helpful thanks

Lol, made this when I was doing my GCSEs last year, originally made it for my class as our teacher never taught coding. Glad you found it helpful. Anyways wish you best of luck with the GCSE as the exams where something last year. Also note, if you know a programming language you can just use that.
