Digital SAT Reading Comprehension: The Complete Guide

Today, I’m going to show you how to master the most important skill for the Digital SAT: reading comprehension.

Each Reading & Writing section contains very challenging passages that you’ll need to tackle in just 32 minutes.

So, this guide will not only save you a ton of time, but also help you easily understand every text.

Let’s dive in.

What is Reading Comprehension?

Reading comprehension is your ability to understand what you’re reading.

Think of it like this: anyone can read a recipe, but comprehension means you understand how the ingredients work together.

Similarly, reading comprehension means that you not just read, but also understand the ideas behind every word.

Therefore, reading comprehension skill is the most important for all kinds of Digital SAT Reading & Writing questions.

From Word in Context, Central idea and details, to Inference, any question needs the ability to quickly understand the meaning of every sentence.

So, how to master reading comprehension skill?

#1: Find the topic

Topic is the main focus of the passage.

So, every sentence of the passage will connect to that overall topic.

Then, knowing the topic can help you get the meaning of the passage more efficiently.

Why?

• First, if you know the topic, you won’t get lost in small details like names or dates.
• Second, you can easily reason the meaning of words, sentences based on the topic.

Finally, knowing the topic helps you avoid wrong answers that focus on unrelated details.

Here are 2 ways to find the topic:

• Read the first and last sentences: the author often mentions the topic in these sentences to introduce or summarize ideas.
• Pay attention to repeated words or phrases: These repetitions help you identify what the author considers most important and wants you to focus on.

Let’s try it:

Example

Moejoh cofounded U-recycle Initiative Africa when she was only a teenager. Moejoh and her team founded the organization to teach young people how their actions affect the environment and why recycling is important. For example, the organization put on an exhibit of art made using recycled materials.

Let’s try 2 ways I mentioned above:

• “Read the first and last sentences”: the first sentence says that Moejoh found an organization.
• “Pay attention to repeated words or phrases”: as bolded, the words “found” and “organization” are repeated.

-> The main topic of the passage is the organization founded by Moejoh.

Here’s another example:

Example

One aspect of in-person shopping that online shopping can't replicate is the opportunity to touch a product before buying it. Does this difference matter? In an experiment, researchers asked one group of participants to touch a mug and a toy, while another group was prohibited from touching the two items. The participants were then asked how much money they'd pay for the items. People who got to touch the items were willing to pay much more money for them than were people who weren't allowed to touch the items.

This passage is more complicated, so let’s take our method to simplify it:

• “Read the first and last sentences”: the first sentence introduces the topic: touching a product before buying it in shopping.
• “Pay attention to repeated words or phrases”: the bolded word “touch” is repeated.

-> The main topic is the effect of touching an item.

#2: Tracing ideas

Digital SAT passage seems dreadfully endless, with many unfamiliar words.

So, it’s easy to get lost in a bunch of college-level information.

Prevent this?

Ignore that information, and focus on the organization of the passage.

Specifically, you look at how that information is connected.

From that relationship, you can reason what the author wants to express.

There are 3 ways to help you do this.

#2.1: Look for transitions

If you have already prep for Transitions questions, you should already know that there are 3 types of transitions:

• Additives provide additional context.
• Adversatives are used to provide contrast.
• Causals signal a cause-and-effect relationship.

So, what’s so important about them?

Transitions act as signposts that guide you through the author’s thought process.

Let’s take a look at the passage below:

Phuc Le

@DSAT16

Example

During the Harlem Renaissance, many artists sought to reclaim and celebrate African heritage in their work. The painter Aaron Douglas, for instance, incorporated motifs from West African sculpture into his murals and illustrations. Similarly, the poet Langston Hughes, in his collection The Weary Blues, drew on the rhythms and structures of blues and jazz music, which have deep roots in African musical traditions.

In this example, the transitions “for instance“ and “similarly“ tell you how the ideas connect.

If you are speed reading and only glancing through the passage, the transitions will still help you guess that:

• the 2nd sentence will provide an example for the 1st sentence
• the 3rd sentence will be similar to the 2nd sentence.

By recognizing these transitions, you can quickly map out how ideas connect and flow throughout the passage.

This makes it much easier to predict the direction of the passage and understand how each sentence relates to the others.

#2.2: Look for punctuations

Besides transition words, punctuation also presents some common signals.

This is like the Writing part, but you can fittingly apply this to reading comprehension.

You can notice that dashes, colons, or parentheses can be used to explain an idea or term.

Let’s take a look at this:

Phuc Le

@DSAT16

Example

Guilds — local associations of artisans and merchants in the same industry — were widespread in France from the medieval period until the late eighteenth century.

Reply Repost Like

-> The pair of dashes explains the word “guilds” right in the middle of the sentence.

Phuc Le

@DSAT16

Example

Few animals are known to spit: among them are humans, cobras, and camels. Spitting serves different purposes for each species, from defense mechanisms to social communication. Llamas (close relatives of camels) also use spitting as a way to establish dominance within their herds.

Reply Repost Like

-> The colon tells you “here’s exactly who I mean” before naming them.

-> The parentheses explain that llamas are related to camels.

#2.3: Skip unimportant words

The SAT passage often contains some words you have never seen before.

They may come from an 18th-century novel, or a list of scientific terms.

In fact, it is really hard to know, or even read, some of these words.

So?

Assign the hard words to symbols.

If you see a long word, call it by the first letter.

If you see a number, call it by variables like x, y, z,…

Then jump to the next one to focus on more important things.

This not only saves your valuable time, but also your reading flow.

Here’s an example:

Phuc Le

@DSAT16

Example

Ruth Asawa was an accomplished artist who worked in many art forms, including her unique tied-wire sculptures, but she was dedicated to more than the creation of art. Asawa also wanted to bring art to children in her hometown of San Francisco, California. To that end, in 1968 she cofounded the Alvarado School Arts Workshop, which brought works of art and artists into public schools, and in 1982 she helped found a San Francisco public arts high school, which was later named after her.

I have bolded some unnecessary words.

You can simplify it immediately and still understand key ideas in the passage.

Specifically, you don’t need to care about the names in the passage (Ruth Asawa, San Francisco, …), or the number (1968, 1982).

You can assign the name to the first letter like (R A, S F, …).

And the number to variables x, y.

Then, this process makes our passage shorter.

Let’s apply to this question:

#3: Common Text Patterns

Scientific passages are one of the most popular types in SAT.

These passages are quite unlikable because of their long and hard sentences.

How can we handle them?

You should look for the structure behind.

For science passages, a few common text patterns often appear again and again in every test.

Hence, knowing these patterns in advance can speed up your reading process.

Let’s get right into them:

#3.1: Old idea -> New idea

Here’s an example:

Phuc Le

@DSAT16

Example

Olms are salamanders that live in underwater caves. Scientists once thought that olms stay in their caves all their lives. However, Raoul Manenti and team claim that olms regularly come to the surface to perform important activities such as finding food.

Reply Repost Like

First, the passage presents an idea that olms never leave their caves.

Then it shows a new idea that olms regularly surface for things like food.

So, our first structure is like: present old idea -> undermine by new idea.

We can recognize this structure through these 3 patterns:

1. [Scientists/many people] [believed/thought] X
2. But/However (adversative transition words)
3. [Named researcher(s)] found Y instead.

Once you spot this shape, you can skip the “old idea” part.

Why?

Because, the question almost always ask about the “new idea” part.

The “old idea” is just the background to provide information.

How about trying this question?

#3.2: Presentation of a Phenomenon + Evaluation of Explanations

Phuc Le

@DSAT16

Example

Genetic studies have led researchers to suggest that turtles are most closely related to the group that includes modern crocodiles. But studies of fossils have suggested instead that turtles are most closely related to other groups, such as the one that contains modern snakes. However, many of the fossil studies have relied on incomplete data sets. For a 2022 investigation, biologist Tiago R. Simões and colleagues examined more than 1,000 reptile fossils collected worldwide. From this large data set, they found clear agreement with the results of the genetic studies.

Reply Repost Like

The passage talks about the origin of turtles.

It presents 2 studies as explanations:

• Genetic studies: turtles ~ crocodiles.
• Fossils studies: turtles ~ snakes.

Then, the passage undermines fossils studies (relied on incomplete data sets).

Finally, it presents another study that supports “genetic studies”.

That’s our second structure: phenomenon → evaluate explanations → support one.

Let’s try this question:

#3.3: Scientific Hypothesis + Study Results

Phuc Le

@DSAT16

Example

Scientists believed that humans hunted woolly mammoths to extinction using spears with special tips called Clovis points. One researcher tested this idea by launching these spears into clay mounds (representing mammoth bodies). The spears only went in a few inches—not deep enough to kill a mammoth. So, the researcher concluded that these spears probably weren’t the main cause of mammoth extinction.

Our next pattern is presented in this passage:

• It shows a hypothesis that humans hunted mammoths to extinction with special tips.
• Then a study was performed and refuted this hypothesis.

So, this is our next structure: a scientific hypothesis -> research about this hypothesis.

Let’s apply to this question:

#3.4: Contrast Between Two Cases

Phuc Le

@DSAT16

Example

Psychologists wanted to test how young children think about rewards and fairness. In an experiment, two teachers handed out rewards while children (ages four to six) watched. The teachers gave out the same number of rewards, but one of them counted the rewards out loud. The children were then asked who was fairer. 73% chose the teacher who counted. The psychologists think that counting showed the children that the teacher wanted to be fair.

Reply Repost Like

This passage talks about how children perceive fairness.

It contrasts two cases:

• Teacher A: gave rewards without counting.
• Teacher B: gave the same rewards but counted out loud.

Then, it shows the result: children chose the teacher who counted as fairer.

So, our next structure is: contrast two cases → show different outcomes → explain why.

Let’s apply to this question:

#3.5: Historical Evidence + Conclusion

Phuc Le

@DSAT16

Example

Archaeologists studying the ancient city of Pompeii in Italy recently discovered a well-preserved food shop known as a thermopolium. The site contains food remains, artworks, and decorations. These items give researchers a better understanding of what daily life in Pompeii may have been like. For example, the archaeologists found a ceramic jar that they believe likely contained a meat and seafood stew.

Reply Repost Like

This passage presents historical evidence and makes a conclusion:

• Historical evidence: archaeologists discovered a thermopolium with food remains, artworks, and decorations.
• Conclusion: these findings help researchers understand daily life in Pompeii.

So, our final structure is: present historical evidence → conclude its significance.

Let’s try this question:

#4: Compress

Have you ever read a hard passage, get confused, and have to reread it again and again?

Here’s the method to prevent that from happening.

You should compress the passage into an easier one.

That is, summarize a tough passage into a simpler one by using your own words.

With this easier version, it’s a piece of cake to reason the true answer.

Here’s an example:

Phuc Le

@DSAT16

Example

Biologists have generally believed that the diet of jaguars consists mostly of land-based mammals, but researchers studying a population of jaguars living in the Brazilian Pantanal, a tropical wetland, claim that jaguars can survive on a diet of more fish and aquatic reptiles than mammals.

@DSAT16

Compress:

Information A: Old belief = Jaguars eat mostly land mammals

Information B: New finding = Jaguars can survive on aquatic animals.

This simplifying process helps your brain focus on other important processes.

Now that the passage is 10-word long, answering the question becomes way easier.

Let’s apply to this question:

#5: Use scratch paper

You may think, “Why do I need to write things down?”, “I can take notes on the screen instead?”

Here’s the reason.

Although taking notes on paper is slower than on a screen, it comes with huge benefits:

• Writing by hand is slower. So, you have more time to think and reason.
• The hand movements in handwriting activate broader brain networks than pressing keys.
• With paper, you can easily design your ideas to match your thinking (e.g. compress it).

Therefore, the next time you practice questions, you should combine both this tip and the previous tip.

Compress the passage, then write it down on your scratch paper.

#6: Familiarize yourself with more topics

This is a ranked list of the most common genres found in 1688 questions from official question bank.

You could see that except for informational trivia, the 4 most common topics are:

• Biology / Life Sciences — 17.4%
• Literature / Fiction & Poetry — 15.0%
• History / Social Studies & Civics — 14.0%
• Art, Humanities & Philosophy — 13.2%

What should you do with this information?

To improve reading comprehension, you should familiarize yourself with these common topics, especially the top four listed above.

Here are some practical ways to do this:

• Read articles and books in biology, literature, history, and art/philosophy.
• Follow science news to stay updated on research and discoveries.
• Explore literary works to get comfortable with different writing styles.
• Learn basic historical events that often appear in SAT passages.

The more exposure to these subjects, the faster you’ll understand SAT passages, even if these passages contain many unfamiliar words.

#7: Improve your English

This might seem obvious, but it’s worth noticing, especially for ESL learners (English as a second language).

Overall English skills are the basis of reading comprehension.

In other words, your reading skill is tied to listening, writing, and speaking skills.

Why?

• First, listening and speaking help you internalize how English flows naturally.
• Second, writing forces you to organize ideas clearly, which helps you understand how authors organize a passage.

I know a guy who didn’t know this when learning for SAT.

He knew that SAT is important when applying, so he just focused on learning it.

He tried to cram tons of vocab and read thousands of passages.

This practice was just effective in the first period.

After that, his reading comprehension skill did not improve.

He could recognize and knew the meaning of every word.

But he still needed much time to understand the overall sentence.

As a result, his score is stuck despite 6 months of hardcore learning.

This situation confused him a lot, so he slowed down to assess the problem.

Finally, he found that “Overall English skills are the basis of reading comprehension.”

Then, he didn’t just practice reading, but also other language skills.

In 2 months, his speed of reading and understanding improved a lot.

Hence, reading comprehension isn’t just about test strategies.

It’s also built on a strong base of English language ability.

Conclusion

With the strategies outlined in this guide, you now have the tools to approach any Digital SAT reading passage with confidence.

While these tips help with all reading questions, you will specifically need them for 2 question types:

• Central Ideas & Details
• Text Structure & Purpose

Check them out, and put your reading comprehension skill to the test.
