In January 2022, we informed you we'd be introducing symbol equations to our specifications for GCSE Combined Science (J250/J260) and GCSE Physics (J249/J259) and in June 2022, we published our updated data and equation sheets.
We can now confirm we've updated our specifications to include the symbol equations, which you can view below:
You can also view and download the specifications from the qualification pages on our website.
We've updated the specifications with the following minor changes to make our word equations clearer:
½ or 0.5 to represent ‘half’
density = mass ÷ volume
density = mass / volume
We’ve also removed repetition in the appendix equation tables and we’ve changed the layout of some word equations for consistency throughout the specification and between corresponding word and symbol equations.
Endorsed and non-endorsed materials use a variety of symbols but for clarity we've created a single-set of defined symbols.
The new symbol equations also appear in our data and equation sheets for first assessment 2023. Where equations are provided to candidates in questions, these will continue to be written in words. Use of the symbol equations by students in their answers is optional.
You can read more about these changes and view the OCR resources available to help you and your students in our blog.
