This is one of the best ways to evaluate your learning progress, while also gaining familiarity with the exam question types, setting style, and mark allocation. It helps students learn how to manage their time effectively and decide the order in which to answer questions, reducing panic caused by time pressure during the exam. In the middle to later stages of revision, dedicated time should be set aside to complete past papers and mock exams. It is recommended to complete at least one full paper each week.

When practicing, it is important to strictly follow the exam time limits and use official answer sheets to simulate real exam conditions. After becoming familiar with the problem-solving process, gradually work on increasing your speed.

Multi-step questions, algebra problems involving multiple variables, or geometry questions with complex diagrams usually require more time. These time-consuming questions should be identified and practiced separately to achieve targeted improvement and increase overall efficiency. During the exam, if a question cannot be solved immediately, mark it and move on, then return to it later if time permits.

IGCSE Mathematics places strong emphasis on the problem-solving process. Students should develop the habit of clearly showing all solution steps, as partial marks may be awarded even if the final answer is incorrect. Pay attention to presenting your work in a clear and logical order so that examiners can easily follow your reasoning.

After completing practice exercises and checking the answers, students should categorize their mistakes into different types and record them in an "error notebook," detailing the cause of each mistake and the correct solution. Common errors include calculation mistakes, incorrect use of formulas, misunderstandings of concepts, or overlooking key conditions in the question.

Revisit and redo these incorrect questions regularly to ensure true understanding. The error notebook is an important revision tool and should be reviewed weekly or monthly to systematically identify and address weaknesses, helping to prevent repeated mistakes.

Students should systematically review the different question types found in past examination papers, become familiar with the characteristics of each type, and identify high-frequency topics for targeted practice. Attention should also be paid to details in question wording, such as key command words (e.g., calculate, prove) and commonly used expressions, to ensure accurate understanding of what the question is asking.

Typical exam questions include straightforward calculation problems, application-based questions, graph or diagram questions, and multi-step reasoning problems.

How can you maximize the value of past exam questions? Students should start with easier problems and gradually progress to more challenging ones. By comparing their answers with the provided solutions, they can link the concepts tested in past papers to the corresponding textbook content, reinforcing what they have learned.
