11 Algorithms (written by myself and taken from the AQA past paper exam) complete with questions regarding data types, return values, calculations, errors etc.
These are designed to be worked through one at a time with students, aiming to have them comment the pseudo-code first, understand what the function/algorithm is intending to do, and then answer the questions that follow.
Revision questions for the topic of flowcharts, 5 questions based around the exam style type, complete with (roughly drawn) answers.
The questions are designed to stretch students to A/A* Grade, covering all input/output/decision choices.
