Edexcel IGCSE Economics 4EC1: Frequent mistakes

Pearson Edexcel Principal Examiner Feedback for Economics 4EC1 highlights recurring errors in definitions, data use, diagrams and evaluation. Addressing these improves your grade.

Fundamental mistakes

Not attempting questions

Leaving answers blank or not attempting questions. No attempt = no marks.

Fix: Attempt every question. Partial credit is possible. Write something relevant.

Multiple choice errors

Putting crosses in multiple boxes on multiple-choice questions. Only one answer is correct.

Fix: One answer per question. Erase fully if changing. Read all options.

Not referring to data

Candidates often ignore data provided in the question. Answers from general knowledge score poorly when use of data is required.

Fix: “According to the table…”, “The data shows…”, “Figure 1 indicates…”

Misreading questions

Not addressing the specific key words asked. Answering a different question.

Fix: Underline key words. “Define” = definition. “Explain” = reasons. “Evaluate” = judgement.

Definition and terminology

Unclear definitions

Inability to produce clear, concise definitions. Definitions should be precise—not examples or descriptions.

Fix: “X is…” + defining characteristics. E.g. “GDP is the total value of goods and services produced in an economy in a year.”

Using examples instead of definitions

For “define” questions, giving examples instead of the definition. Examples alone do not define.

Fix: Give the definition first. Examples can support but not replace.

Confusing concepts

Incorrect understanding—e.g. confusing price elasticity of demand with the relationship between price and quantity, rather than proportionate changes.

Fix: PED = % change in Qd ÷ % change in P. It measures responsiveness, not direction.

Incorrect formulas

Stating formulas incorrectly or incompletely. E.g. PED formula wrong or incomplete.

Fix: Learn formulas precisely. PED = ΔQ/Q ÷ ΔP/P.

Analysis and evaluation

Yes/no to evaluation questions

Answering “yes” or “no” to questions requiring evaluation. Evaluation needs reasoning and evidence.

Fix: “To a great extent… because…”, “However…”, “On balance…”

Lack of balanced arguments

Higher-level skills questions require balanced arguments—both sides before a conclusion.

Fix: “On one hand…”, “On the other hand…”, “However…”, “Therefore…”

Not going beyond simple explanations

Failing to use economic concepts appropriately. Superficial explanation.

Fix: Use correct terminology. Link to theory. Develop points.

Not placing answers in context

Answers not placed in context—e.g. real-world application, specific scenario.

Fix: Relate to the question context. Use examples if helpful.

Data and diagrams

Little or no reference to data

Responses with little or no reference to provided data. Address all parts (e.g. exports and imports, not just one).

Fix: Quote figures. Compare. Interpret trends.

Diagram errors

Not labelling new shifts and equilibrium points on supply and demand diagrams. Shifting both curves when only one should shift.

Fix: Label axes. Label curves. Show shift with arrow. Mark new equilibrium. Only shift the curve affected by the factor.
