Each Core Content section covers a specific topic, such as Angles on Parallel Lines or Dividing Mixed Numbers.

Every section starts with a short video introducing the topic and walking through an example problem.

Questions start at a basic level. As students answer questions correctly, the difficulty increases. The section will end when the question limit is reached, which is typically between five and eight questions. More capable students will spend most of the section answering more difficult questions.

On any question, students can click ‘Get Help’ to enter ‘Practice Mode’. This breaks the problem down into individual steps and tests students on the key aspect of each step. Students are taken all the way to the final answer so they can see exactly how the problem should be solved.

After completing a step-by-step walkthrough, students are given another question in the exact same format, just with different numbers. This time, there's no step-by-step walkthrough available, only a support video if they're stuck. If they get the question wrong, they can try again once more, before being taken through the walkthrough.

After completing any Core Content sections in an assignment, students move on to exam-style questions to practise their exam technique.

Rather than just entering a final answer, students are expected to write out their full workings on paper as they would in an exam, then submit a photo of them. Students who aren't able to take a photo can type their workings instead.

When a student submits their response to the question, their full workings and answer are automatically marked against a mark scheme as an examiner would. The student can then see exactly where they earned their marks and get a full analysis of their answer before progressing to the next question.
