What examiners said
Comprehensive responses • Most candidates gave their response using either pseudocode or Python. • Many candidates initialised their arrays at an appropriate place in their program. • Most candidates allowed correct inputs to take place within their program and these inputs were validated. • Most candidates wrote code to enable the options for the survey to be input and stored. • Most candidates e...
— Examiner report, February/March 2026, 0478/22 Q9 (Cambridge)
Candidates were required to complete an extended program to meet a set of requirements given in a scenario based on adding and outputting membership details of a sports club. The program was to display a menu to allow three options: • add a new member by entering a new membership code, chosen by the new member, with the program checking to make sure it had a length of six characters and that it h...
— Examiner report, February/March 2025, 0478/22 Q10 (Cambridge)
Candidates were asked to meet three requirements. Requirement 1 was to find the maximum, minimum and average temperature reading for each day. Requirement 2 was to find the maximum, minimum and average temperature reading for the week and requirement 3 was to output the temperatures for each day and the week. Requirement 1 was quite well attempted by most candidates who used a nested loops and th...
