The Challenge

BBC Bitesize wanted a 20-question quiz that helps GCSE students identify the areas that should be prioritised during their home learning.

Creating an unintelligent data-collection quiz first was not an option, it had to be clever from the point of conception. However, any algorithm we created was always going to be inferior to one that is informed by data collected once the product goes live. We needed an algorithm that is intelligent without data, and flexible enough to…
