Study Tips
- 1
Define every key term precisely — many exam marks come from accurate use of subject terminology.
- 2
Apply concepts to real-world scenarios; application questions dominate modern exams.
- 3
Work through past papers under timed conditions — familiarity with question style is half the battle.
- 4
Practice with past papers from your specific exam board (AQA, Edexcel, OCR) — question styles differ meaningfully.
- 5
Learn the command words (describe, explain, evaluate) — each demands a different type of answer.
Past Exam Questions
Define the key terms associated with Algorithms and explain why they matter in this subject.
Apply the concept of Programming Fundamentals to a realistic scenario, explaining your reasoning step by step.
Evaluate the strengths and limitations of Data Representation, using evidence to support a clear, balanced conclusion.
Common Mistakes to Avoid
- ✕
Ignoring the marks allocated per question — a 2-mark answer doesn't need a paragraph.
- ✕
Never practicing under timed conditions before the real exam.
- ✕
Confusing similar key terms that examiners deliberately test against each other.
