Examiner Tips

Expert advice for maximising your marks

💡Always show your working step-by-step in calculations to gain method marks even if the final answer is incorrect.
💡When solving problems, clearly state the mathematical technique used and why it's appropriate for the computing context.
💡For logic tasks, double-check truth tables by verifying each row systematically; one mistake can cascade.
💡Practice converting numbers between different bases until it becomes second nature, as this is a common exam task.
💡Use computing scenarios (e.g., data compression, error detection) to frame your answers, demonstrating applied understanding.

Common Mistakes

Pitfalls to avoid in your exam answers

Confusing logical operators such as treating AND as OR in truth tables.
Misapplying order of operations in binary arithmetic (e.g., forgetting carry values).
Assuming probability calculations are always straightforward without considering dependent vs. independent events.
Misunderstanding that binary representations have fixed bit-lengths, leading to overflow errors.
Failing to connect mathematical formulas to real computing applications, treating them as abstract.
