How do I quickly find the questions students struggled with most?

Last updated: October 15, 2026

To find the questions or exercises your students found hardest, use the exercise filter in the results analysis of an assessment.

🧭 In your assessment’s “Insights” tab, in the “Learning Analytics” section:

  • Click the “The entire assessment” dropdown to filter the results by exercise (you can check one or more).

  • You can then compare how students did from one exercise to the next, with their mastery level on each skill involved.

📊 This helps you quickly spot:

  • The least successful exercises,

  • The most discriminating exercises, the ones that best separate students who’ve got it from those who haven’t,

  • Skills shared by several exercises, for a view across the whole assessment.

The “Observations” view, next to “Skills”, adds the most common error types, with how many students each one affects.

🔎 If you grade with scores, you can also compare questions with each other: in the “Results” section, click “View detailed results”. The “Class results details” table shows each student’s score, question by question.

💡 With the “Explore with Ed” button, Ed can also tell you which questions were the least successful or the most discriminating, so you can target exactly what to reteach.
