How are predicted grades calculated on Atom Home? 

What are predicted grades?

Predicted grades estimate the GCSE grade you are likely to achieve in each subject, based on your performance in recent practice and past papers.

For each subject, your predicted grade is the average of the 3 most recent papers you’ve completed in that subject, as well as your performance in the practice questions.

Predicted grades are useful because they:

  • Give you a clear snapshot of your current performance.

  • Highlight subjects that may need extra attention.

  • Encourage reflection after completing papers to help focus your revision.

 

How are grades assigned to each paper?

When a GCSE paper is marked, your percentage score is converted into a predicted GCSE grade.

Here’s how it works:

  • Your percentage score is mapped to a GCSE grade using real exam board grade boundaries.

  • For past papers, we use the official boundaries published for that specific paper.

  • For practice papers we’ve created, we use an average of the grade boundaries from the past paper counterparts.

 

What are predicted topic grades? 

These individual topic grades give you a more granular breakdown of your topic-specific performance. They give you a quick snapshot of your current attainment in a particular topic

How does my confidence rating work? 

We use a confidence rating to show you how certain we are that the predicted grade you've achieved for that particular topic is accurate. We do this to make sure that the grade is as representative of your attainment across all that topic's content as possible. The more questions you answer in a particular topic, the higher this confidence rating will be. 

This ensures your predicted grades reflect both your current ability and the standards of real exams.
