Top Study Tips for AQA AS Level Computer Science (7516)
1. Start Early and Plan Ahead
Avoid last-minute cramming. Create a revision schedule that includes all topics and spreads your study time over several weeks. Use our topic-based notes to cover one section at a time.
2. Use Active Recall
Reading alone isn’t enough. Test yourself regularly. After reading a section from our AQA AS Level Computer Science (7516) revision notes, close the notes and try to recall the key points. Use flashcards or quiz yourself.
3. Practice Past Papers
Practice makes perfect. Use the exam-style questions provided on Exam Papers Practice to get used to the format and timing of the actual exam.
4. Explain Concepts Out Loud
Teach someone else, or pretend you’re teaching. Explaining a topic out loud helps you discover gaps in your understanding and reinforces memory.
5. Use Visual Aids
Many Computer Science topics are easier to understand with diagrams. Our notes include flowcharts, tables, and graphs to make learning more intuitive.
6. Review Regularly
Don’t just read a topic once. Revisit each section a few days later to reinforce your memory. Use spaced repetition techniques to help retain the information long-term.
