The pre-release tasks are open ended to allow more-able students to expand their program or programs. They can also be interpreted in different ways, as there is no one single solution to the tasks. The purpose of the tasks is to allow students to develop their problem solving and programming skills, to create a suitable solution(s) to the tasks. As you will see in the Mark Schemes of previous papers, the answers shown are only one example of a suitable solution.
Please be aware that the pre-release tasks are live examination material so we are not in a position to answer specific queries relating to them.
