Theory, pseudocode, programming and problem solving for both written and practical papers.
Our approach
Computer Science combines theory and coding. We cover data representation, hardware and networks, then build real problem-solving skill through pseudocode, trace tables and Python programming practice.
Move from reading code to predicting and explaining its behaviour. Trace a small example, test boundary values and then write an algorithm that meets the stated requirements.
Try a practice question
An original learning exercise, not an official exam question.
Start Total and Count at 0. For each score in 40, 50, 75, add the score to Total and increase Count if the score is at least 50. Find the final values.
Total = 165 and Count = 2. The score of exactly 50 is included.
Common mistake: Resetting Total inside the loop loses earlier scores. Using ‘greater than 50’ instead of ‘at least 50’ misses the boundary case.
