Multiple choice questions
There are two papers for each tier of entry, Foundation and Higher. Each paper is split into two sections, Section A and Section B.
| Section | Type(s) of questions | Marks per question |
| A | Multiple choice | 1 |
| B | Short answer, Extended response | 1 to 5, 6 |
| Section | A |
|---|---|
| Type(s) of questions | Multiple choice |
| Marks per question | 1 |
| Section | B |
|---|---|
| Type(s) of questions | Short answer, Extended response |
| Marks per question | 1 to 5, 6 |
The short answer questions contain different styles, including:
- structured questions
- maths questions
- practical questions
Multiple choice questions appear in both exam papers, and at both tiers. Multiple choice questions are asked as questions, often starting with 鈥榃hat is...?鈥 or 鈥榃hich of these...?鈥.
You have four options to choose from in a multiple choice question. You must only choose one of these options, by writing your answer (A, B, C, or D) in a box.

Sample question 1 - Foundation
Question
A student investigates the reaction between sodium carbonate and dilute nitric acid.
She measures the reaction time with four different concentrations of acid.
She does all the experiments using the:
- same temperature
- same mass of sodium carbonate
- same volume of acid
Look at her results.
| Concentration | Reaction time (s) |
| A | 41 |
| B | 74 |
| C | 135 |
| D | 67 |
| Concentration | A |
|---|---|
| Reaction time (s) | 41 |
| Concentration | B |
|---|---|
| Reaction time (s) | 74 |
| Concentration | C |
|---|---|
| Reaction time (s) | 135 |
| Concentration | D |

Sample question 2 - Higher
Question
Hydrogen reacts with iodine to form hydrogen iodide:
H2(g) + I2(g) 鈬 2HI(g) (forward reaction is endothermic)
The reaction reaches equilibrium.
Which of the following changes in the reaction conditions will cause the position of equilibrium to move to the right?
A increase in pressure
B decrease in pressure
C increase in temperature
D decrease in temperature
