How to Read dMAT Academic Passages

The General Academic Module is not just a knowledge test. The official sample shows short academic teaching passages followed by questions that require application, transfer, and judgement.

That means your reading method matters. A student who knows the topic but reads carelessly can still miss questions. A student who has never seen the topic before can often solve the item if they quickly identify definitions, assumptions, variables, and relationships.

Use this article after the dMAT General Academic Module guide. For Core Module practice, start with Figure Sequences, Mathematical Equations, and Latin Squares.

Last reviewed: 1 August 2026. This article is based on the official General Academic Module sample structure and general academic reading guidance. All practice questions below are Think Mile original and are not official dMAT questions.

Direct Answer

To read dMAT academic passages well, use this sequence:

1. Identify definitions.
2. Mark variables mentally.
3. Identify assumptions.
4. Separate facts from examples.
5. Determine causal or proportional relationships.
6. Read the question before calculating.
7. Eliminate options that contradict the passage.
8. Estimate before doing exact arithmetic.

This method works across the official sample topics: vectors, hydrostatics, optimal order quantity, and research strategies.

Official Evidence

The official General Academic Module sample includes four different passage types:

The common pattern is not "memorise this topic." The common pattern is:

• receive compact academic instruction;
• extract the model;
• apply it to a new question;
• select one correct answer from four options.

The dMAT Passage Reading Method

1. Identify definitions

Definitions tell you how the passage uses a term. Do not rely only on your prior meaning.

Examples:

• In a vector passage, "scalar product" may be defined by a formula.
• In research methods, "deductive" may be defined as testing a theory.
• In EOQ, "holding cost" may be defined as cost per unit stored.

Ask:

What does this term mean inside this passage?

2. Mark variables mentally

When a passage gives a formula, name the variables in your head.

Example:

output = incoming power x efficiency

Mental labels:

• output is what we calculate;
• incoming power is given;
• efficiency must be converted from percent to decimal.

You cannot take notes, so use short labels.

3. Identify assumptions

Assumptions limit when a model applies.

Examples:

• EOQ may assume constant demand.
• A hydrostatics question may assume an incompressible liquid.
• A research design may assume the goal is theory testing.

Many wrong options violate assumptions.

4. Separate facts from examples

Passages often include examples to illustrate a rule. Do not treat the example as the rule.

Example:

If a passage says "For example, a submarine can change its buoyancy," the broader rule may be about density, displaced water, or volume. The submarine is only one case.

5. Determine the relationship

Ask whether the relation is:

• direct: when X increases, Y increases;
• inverse: when X increases, Y decreases;
• threshold-based: a change matters only past a limit;
• categorical: choose the correct type or method;
• causal: one factor produces a change;
• correlational: two things move together, but cause is not proven.

6. Read the question before calculating

Do not calculate everything. First ask:

• Is this asking for a number?
• Is it asking for a concept?
• Is it asking what follows from the passage?
• Is it asking which method fits a scenario?

The question tells you what part of the passage matters.

7. Eliminate contradictions

Wrong options often contradict one sentence in the passage.

Eliminate options that:

• reverse the relationship;
• ignore an assumption;
• use the wrong unit;
• treat correlation as causation;
• confuse qualitative with quantitative;
• choose a memorised fact that the passage does not support.

8. Estimate before exact arithmetic

Before calculating, predict the direction.

Example:

If temperature reduces efficiency, a hotter panel should have lower output. If your calculation gives higher output, check your work.

Worked Example

Think Mile original passage:

A water filter removes particles from water. Its removal efficiency is the percentage of particles removed in one pass. A filter has 80% efficiency for large particles and 50% efficiency for small particles.

If 1,000 large particles enter the filter, 800 are removed and 200 remain. If the remaining water passes through a second identical filter, the second filter removes 80% of the particles that remain after the first pass, not 80% of the original 1,000.

Question:

After two passes through identical filters, how many large particles remain from the original 1,000?

A. 40
B. 100
C. 160
D. 200

Solution:

First pass:

• 80% removed from 1,000 = 800 removed.
• 200 remain.

Second pass:

• 80% removed from the remaining 200 = 160 removed.
• 40 remain.

Answer: A. 40

Reading skill tested:

The key sentence is "the second filter removes 80% of the particles that remain after the first pass." The trap is applying 80% twice to the original total.

Original Practice Passage

This is Think Mile original practice, not official dMAT material.

Passage: Urban Tree Cover and Surface Temperature

Researchers study surface temperatures in three city districts during summer afternoons. They record tree-cover percentage and average surface temperature.

Tree cover is the percentage of land area shaded by tree crowns when viewed from above. Surface temperature is measured in degrees Celsius using thermal images.

The researchers find the following pattern:

They propose that higher tree cover may reduce surface temperature by shading pavement and increasing evaporation from leaves. However, they also note that other factors, such as building density, road material, wind, and time of measurement, may affect surface temperature.

Questions

1. Which statement best describes the pattern in the table?

A. Higher tree cover is associated with lower surface temperature.
B. Higher tree cover is associated with higher surface temperature.
C. Tree cover and surface temperature are identical measures.
D. District A has the lowest surface temperature.

2. Which option is a possible causal mechanism mentioned in the passage?

A. Tree cover is measured from above.
B. Thermal images measure temperature.
C. Trees shade pavement and increase evaporation from leaves.
D. District C has 40% tree cover.

3. Why should the researchers be careful before claiming that tree cover alone caused the temperature difference?

A. The table has no temperature values.
B. Other factors such as building density and road material may affect temperature.
C. Tree cover cannot be measured.
D. District A has more tree cover than District C.

4. If a new District D has 30% tree cover, what is the safest conclusion from the passage?

A. Its surface temperature must be exactly 37 C.
B. Its surface temperature must be higher than District A.
C. It may have lower surface temperature than a district with 10% tree cover, but other factors also matter.
D. Tree cover will have no relationship with temperature.

5. Which research design would best test whether increasing tree cover reduces surface temperature?

A. Measure only one district once.
B. Compare many similar street segments before and after tree planting while controlling for road material and building density.
C. Ask residents whether they like trees.
D. Count the number of buildings but ignore temperature.

6. What is the difference in surface temperature between District A and District C?

A. 5 C
B. 8 C
C. 10 C
D. 15 C

Solutions

1. A. As tree cover rises from 10% to 40%, surface temperature falls from 43 C to 35 C.

2. C. The passage explicitly mentions shading pavement and evaporation from leaves as possible mechanisms.

3. B. The passage lists other factors that may affect temperature. This is a confounding-factor issue.

4. C. The pattern suggests higher tree cover may be linked with lower surface temperature, but the passage warns that other factors matter.

5. B. A stronger causal design compares similar places before and after an intervention while controlling for other variables.

6. B. 43 C - 35 C = 8 C.

Frequently Asked Questions

Should I read the whole passage first or the questions first?
Do a fast first pass through the passage, then read the question. After that, return only to the relevant section.

What if I do not know the topic?
Use the definitions and formulas in the passage first. The General Academic Module rewards transfer, not only prior subject memory.

Are all formulas guaranteed to be provided?
No. Some formulas appear in the sample, but the official material does not promise that every needed formula will always be supplied.

How do I avoid overthinking?
Classify the question: definition, formula, graph, scenario, assumption, or method. Then solve that task only.

What should I study next?
Continue with focused Part 2 concept guides: vectors, hydrostatics, EOQ, and research methods.
