Exam code: 0455 & 0987
How do I answer an IGCSE Economics multiple-choice question?
One-mark MCQs appear in Paper 1 only
There are 40 MCQs
You can see more information on the Paper 1: Multiple Choice page
Systematic steps to help you succeed in MCQ exams
1. Read the question stem carefully
Focus on exactly what the question is asking
Identify whether it is testing:
a definition
a numerical idea
a diagram
a cause-effect relationship
2. Underline key words in the stem
Look for words such as:
increase / decrease
most likely / best explains
scarcity / opportunity cost / elasticity
These help you avoid misreading the question
3. Cover the options and think of the answer first
Try to answer from your own knowledge before looking at the choices
This helps you avoid being misled by distractors
Examiner Tips and Tricks
Distractors are written to trap common misconceptions
Most wrong options are designed to reflect:
misunderstanding of a definition
confusing a shift with a movement
mixing up cause and effect
ignoring key words like “fall”, “less elastic”, “opportunity cost”
If an option sounds nearly right but slightly off, it’s probably the distractor
4. Eliminate obviously incorrect options
Remove answers that:
contradict definitions
do not match the diagram
mix up micro and macro concepts
contain extreme words like “always” or “never”
You should aim to narrow it down to two choices
5. Compare the remaining options logically
Ask yourself which option:
directly fits the economic concept
follows the correct cause → effect chain
matches the data or numerical relationship
The best answer is the one that is always true, not just sometimes true
Examiner Tips and Tricks
The correct answer must be true in every possible scenario the question describes
If an answer is:
only true sometimes
dependent on extra assumptions
true for a special case
it is almost certainly not the correct response
6. Use diagrams where relevant (mentally)
For demand and supply questions:
visualise the shift
think about the direction of price and quantity
For elasticity questions:
imagine steep vs shallow curves
You don’t need to draw diagrams on the paper - but visualising them helps
7. Check the units in numerical questions
Percentage?
Index number?
Millions or billions?
Make sure your mental calculation matches the scale given
8. Make a decision - and move on
Do not spend too long on any one question
You have approximately 1.5 minutes per question
If you can't decide between two answers, choose the one that fits economic logic, not the one that sounds appealing
Worked Example
The table shows the quantity that producers are willing to supply at different price levels.
price ($) | quantity supplied |
|---|---|
120 150 180 | 20 40 80 |
If the price increases from $120 to $180, what would be the price elasticity of supply?
A. 0.16
B. 4
C. 6
D. 60
Mark Scheme & Guidance
C is correct as substituting the values into the PES formula (% change in QS / % change in price) results in the following: 3 / 0.5 = 6
A is incorrect as 0.16 is an incorrect application of the PES formula
B is incorrect as a value of 4 is an incorrect application of the PES formula
D is incorrect as a value of 60 refers to the absolute changes in price and quantity and not the calculated PES using percentages
