This article is on the C-Score, Carousel's Responsive Quizzing metric for Gold and Platinum users.
If C-Scores are not loading when you are selecting questions for a quiz, you may need to do a hard reload of your browser tab (PC: CTRL + F5 / Mac: COMMAND + SHIFT + R)
What is a C-Score?
The C-Score is a metric between 0-15 to help facilitate 'Responsive Quizzing', by giving you a score which takes into account each of the following 3 areas for each question:
How many times it has been included in a quiz (for the class/year group selected);
How many weeks ago it was last included in a quiz, (for the class/year group selected);
The average % correct from the most recent quiz with 1+ responses where the question was included (for the class/year group selected).
A higher C-Score indicates a question which e.g. may not have been asked for a long time, or had a low average % in the most recent quiz, or a hasn't been included many times. A high score can indicate a combination of the above 3 factors too.
Where do I see C-Scores and how do I use them?
When you are creating a new quiz and click SELECT QUESTIONS, you will see a drop-down which allows you to select a Class OR a Year Group to pull in C-Score data from:
You can click on the C-SCORE column to organise the questions by their C-Score from high to low or low to high.
As you select your questions, you will also see an the average C-Score of those questions at the top of the table:
When you hover over the coloured line (the longer and darker the line, the higher the question's C-Score), a pop-up will tell you the C-Score for that question, and the breakdown of its score by the 3 information points:
How are C-Scores Calculated?
- Scores are calculated using any quizzes that have been set.
- Study pack quizzes are not considered in the calculations.
- C-scores are only assigned if 1+ question from the same topic has been used in a quiz for the class/year group selected.
- If a question has not been used in a quiz for the class/year group selected but other questions from the same topic have been used then the question is assigned 15 points.
- Questions associated with topics that have never been used in a quiz before have a null c-score (represented as a
