They know that √2 is exactly 1.41421356... but they keep it as √2 just to be safe.

If you calculate the volume of a sphere as 113.1 cm³ (using 3.14 for π), OCR might give you 0 marks. Why? Because the true answer is 36π cm³ . By rounding, you introduced an error. OCR wants the truth , not the decimal. Gcse Maths Ocr

Consider (that nasty topic with √2 and √3). Most syllabi teach you to simplify them. OCR, however, loves to hide surds inside the Pythagoras theorem questions about phone screens. They know that √2 is exactly 1

Let’s start with the paper codes themselves: J560 (Foundation) and J560 (Higher). But look closer at the OCR problem-solving questions. They aren't just asking you to solve for x ; they are asking you to be a detective. OCR wants the truth , not the decimal

Wrong. Dead wrong.

Why is this interesting? ChatGPT, self-driving cars, and weather forecasts don't solve equations perfectly—they iterate. They guess, check, and refine. OCR is teaching you machine learning in disguise.

Here is the most interesting fact of all. In the real world, an engineer who gets 100% on an AQA paper might build a bridge that collapses because they rounded pi. An engineer who scrapes a pass on OCR?
