C-Scores: Using Responsive Quizzing

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:

Top Tip

A quick and easy way to use C-Scores to select highly impactful questions, is to put on a filter with a minimum of 9, and then click `SELECT RANDOM`.

How are C-Scores Calculated?

• Scores are calculated using any quizzes that have been set.
• Study pack quizzes are not considered in the calculations.
• Platinum users can choose to include Whiteboard quizzes in the C-Score 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, then the question is assigned 15 points.

Carousel's Education Director, Adam Boxer, talks you through C-Scores, and how they can turbo-charge your quizzes.
