Top Exam Board Tips
- Read each question carefully and identify what is being asked.
- Use estimation to check if your answer is reasonable.
- Show all steps in your calculations.
- Show all stages of working; marks are awarded for method even if the final answer is incorrect
- When solving equations, always check your solutions by substituting back into the original equation
- For calculus questions, clearly identify the function to differentiate/integrate and state the rule used
- In matrix transformation questions, multiply the transformation matrix by the position vector correctly, checking the order of multiplication
- Show all steps in your working to secure method marks, even if the final answer is wrong
- Always check the discriminator before stating the number of real roots of a quadratic
- When integrating, include the constant of integration for indefinite integrals, and use correct notation for definite integrals
Common Mistakes to Avoid
- Misreading questions or not understanding the context.
- Making basic arithmetic errors.
- Not showing working out for calculations.
- Confusing the signs when completing the square or applying the quadratic formula
- Misapplying the chain rule, particularly when differentiating composite functions of the form (ax+b)^n
- Incorrectly multiplying matrices (e.g., ignoring non-commutativity or mismatching dimensions)
- Forgetting to include the constant of integration in indefinite integrals
- Failing to check the discriminant when finding real roots, leading to invalid solutions
