Edexcel IGCSE Geography Past Papers

Common mistake: A recurring issue is students only stating a factor without building a logical sequence of "this leads to". For "explain one..." questions, many fail to develop the point enough to earn all available marks.

How to solve it: Use the number of marks as a guide for the required depth. A 3-mark "explain" question requires an initial point followed by two distinct links in an explanatory chain (e.g., "Heavy rain leads to saturated soil (1), which increases surface runoff (1), leading to a rapid increase in river discharge (1)").

Common mistake: Students frequently use these terms interchangeably. For example, they might suggest an "accurate" method when they are actually describing a way to increase "reliability".

How to solve it: Learn the specific definitions: Accuracy is how close a measurement is to the true value (e.g., using better equipment), whereas reliability is about consistency and repeatability (e.g., increasing sample size or repeating the test)

Common mistake: Many students struggle to distinguish between different stages of fieldwork, such as confusing data collection methods with data presentation or data analysis techniques.

How to solve it: Be confident in explaining what happens at each stage. For example, a questionnaire is a collection method, a bar graph is a presentation technique, and "comparing results" is a simplistic analysis technique.

Common mistake: For the longer response questions, students often describe the data shown in the resource but fail to meet the "analyse" command word.

How to solve it: Investigation of an issue by breaking it down into components and making logical, evidence-based connections between them. While an evaluation statement is not strictly required at the end, providing a judgement on the significance of different factors is essential for the highest marks.

Common mistake: Only using one resource when the question directs you to two, or describing a graph without linking it to geographical concepts.

How to solve it: Use resources as a starting point to develop your argument. Link specific evidence from the resource (e.g., data points or map regions) to your own knowledge and understanding (AO2).

Common mistake: Students frequently spend too much time on low-mark questions, leaving insufficient time for high-tariff extended responses.

How to solve it: Use the mark tariff as a guide. A 2-mark ‘describe’ question only needs a basic point and one development. Save your depth and structured discussion for the 8 and 12-mark questions.
