SAT Reading & Writing Brief Overview

Unlike the old SAT, there’s no separate section for Reading or Writing on the digital SAT. Instead, the test combines both into one Reading & Writing section, split across two “modules.” You can jump to our breakdown of the SAT Sections for more info, but we’ll summarize the key bits below.

Each module has the same structure: 32 minutes for 27 questions. The reason College Board splits the section into separate modules has to do with the “adaptive” testing system they use. In a nutshell, the second module’s difficulty will depend on your performance on the first module.

Do better on module 1, and you’ll get harder questions on module 2. It’s important to note that you’ll still see the same types of questions, just at different degrees of difficulty.

One key thing to remember about digital SAT scoring is that not all questions are worth the same number of points. In essence, harder questions are worth more points than easier ones, so you want to ensure that you’re prepared for the toughest questions the SAT can throw at you. For a full breakdown of the digital SAT scoring system, including how the adaptive testing works, check out our digital SAT score guide here.

Question Types on SAT Reading

According to College Board’s official categories, the SAT Reading & Writing Section tests:

Information and Ideas
Craft and Structure
Expression of Ideas
Standard English Conventions

The first two categories correspond to the “Reading” questions; the second two categories are the “Writing” questions.

If that’s not confusing enough, each of the main categories has specific subcategories that–more or less–correspond to question types.

So, College Board uses “Information and Ideas” questions to test:

Central Ideas and Details
Inferences
Command of Evidence

And “Craft and Structure” questions to test:

Words in Context
Text Structure and Purpose
Cross-text Connections

Confused by these categories and subcategories? You’re right to be: it’s a terrible system! It’s not just that the categories are broad and generic (“Information and Ideas” isn’t all that helpful); it’s also that these subcategories don’t actually make clear what skills are being tested.

If you want to really understand the SAT, these College Board categories are less important than the underlying skills being tested by the SAT Reading & Writing section. Understand those skills, and you’ll understand what you need to do.

That’s why we’ve done our best to translate these College Board categories into more recognizable question types (you can read more about these on our guide to SAT Reading here), but you can really think of the main question types for Reading coming down to:

Literal Comprehension
Logical Reasoning

Literal Comprehension questions correspond to College Board’s “Words in Context, Test Structure and Purpose, Cross Text Connections, and Central Ideas and Details” categories.

Logical Reasoning questions are really what College Board means when they refer to “Inference” and “Command of Evidence” based questions.

It’s these logical reasoning questions that are, by far, the SAT’s most difficult questions. Even the smartest students we work with routinely struggle to understand and approach them! That’s why we’re putting together a guide on how to crack these questions.

Hardest SAT Reading Questions Examples

We’re going to pick some of the toughest examples of these Logical Reasoning (or “Inferences” and “Command of Evidence”) questions, teach you how to recognize them, and break down how the SAT wants you to approach them.

SAT Reading Question Example 1

Let’s start with an example of what College Board calls an “Inference” question, sourced from the College Board Digital SAT Question Bank:

Marta Coll and colleagues’ 2010 Mediterranean Sea biodiversity census reported approximately 17,000 species, nearly double the number reported in Carlo Bianchi and Carla Morri’s 2000 census—a difference only partly attributable to the description of new invertebrate species in the interim. Another factor is that the morphological variability of microorganisms is poorly understood compared to that of vertebrates, invertebrates, plants, and algae, creating uncertainty about how to evaluate microorganisms as species. Researchers’ decisions on such matters therefore can be highly consequential. Indeed, the two censuses reported similar counts of vertebrate, plant, and algal species, suggesting that _____

Which choice most logically completes the text?

A. Coll and colleagues reported a much higher number of species than Bianchi and Morri did largely due to the inclusion of invertebrate species that had not been described at the time of Bianchi and Morri’s census.

B. some differences observed in microorganisms may have been treated as variations within species by Bianchi and Morri but treated as indicative of distinct species by Coll and colleagues.

C. Bianchi and Morri may have been less sensitive to the degree of morphological variation displayed within a typical species of microorganism than Coll and colleagues were.

D. the absence of clarity regarding how to differentiate among species of microorganisms may have resulted in Coll and colleagues underestimating the number of microorganism species.

This kind of question can be brutal to tackle: how do you decide which of the answer choices is the “logical” one?

The key to understanding these is to think of these passages as logical arguments. In essence, they’re made up of two pieces: evidence and a conclusion. The conclusion must always be supported by the evidence.

When the Digital SAT asks you to “most logically complete the text,” they are always asking you for the conclusion. The only way to get to the correct answer is to identify all of the relevant evidence, and then identify which answer option matches up with it.

So, let’s do a detailed breakdown of this question.

Start by identifying all the evidence:

2010 census has almost 2x the number of species as 2000 census.
This difference is only partially explainable by the new invertebrate species.
Another factor is that there is uncertainty about how to define microorganisms as species.
Researchers’ decisions on how to do so are highly consequential.
The two censuses reported similar numbers of vertebrate, plant, and algal species.

When we say evidence, we don’t just mean the numbers and stats: the evidence is all of the relevant facts leading up to the conclusion!

So, now that we have our evidence gathered, all we need to do is compare each answer option to the evidence and ensure that it is consistent.

Let’s take a look at our four answer choices:

Answer option A is inconsistent with our second piece of evidence, which specifically stated that the “new invertebrate” species could only “partially” explain the difference.
Answer option B is consistent with all the evidence! Remember, we need to explain why one census had so many more species than the other one, even though both had similar numbers of “vertebrate, plant, and algae species.” The difference must be in the microorganisms, since our evidence tells us that there is uncertainty in how to define microorganisms, and that the scientists are the ones who make those decisions. If the first census considered many microorganisms to be the same species, but the second census considered them all to be different species, then of course the second study would have more total species. B is correct.
Answer option C is inconsistent with the evidence, because it doesn’t explain why the second census had so many more species. All C talks about is differences within one species, which has no bearing on the total number of species recorded by the census.
Answer option D is inconsistent with the evidence because it says Coll’s study underestimated the total number of species, but we know that Coll’s study is the one that had more species than the other study.

It’s still not an easy question, but this method is your best bet at eliminating wrong answer choices and landing on the correct one.

The key here is not, as College Board would have you believe, “inference.” It’s just the opposite: you need to stick as close as possible to the literal evidence, and ensure the answer choice you pick matches with all the points of evidence.

To recap the method:

When a digital SAT Reading question asks you to “logically complete the text,” you must:

Identify all of the evidence in the passage.
Identify which answer option is consistent with all the evidence.

These can still be tricky, but using this method will dramatically improve your chances! The other way of really increasing your chances at a great or perfect score?

SAT Reading Question Example 2

Not all SAT Logical Reasoning questions will ask you to “logically complete” the text. But they all expect you to use the same method we’ve just discussed. Let’s take a look at an example from what College Board calls “Command of Evidence:”

Mosasaurs were large marine reptiles that lived in the Late Cretaceous period, approximately 100 million to 66 million years ago. Celina Suarez, Alberto Pérez-Huerta, and T. Lynn Harrell Jr. examined oxygen-18 isotopes in mosasaur tooth enamel in order to calculate likely mosasaur body temperatures and determined that mosasaurs were endothermic—that is, they used internal metabolic processes to maintain a stable body temperature in a variety of ambient temperatures. Suarez, Pérez-Huerta, and Harrell claim that endothermy would have enabled mosasaurs to include relatively cold polar waters in their range.

Which finding, if true, would most directly support Suarez, Pérez-Huerta, and Harrell’s claim?

A. Mosasaurs’ likely body temperatures are easier to determine from tooth enamel oxygen-18 isotope data than the body temperatures of nonendothermic Late Cretaceous marine reptiles are.

B. Fossils of both mosasaurs and nonendothermic marine reptiles have been found in roughly equal numbers in regions known to be near the poles during the Late Cretaceous, though in lower concentrations than elsewhere.

C. Several mosasaur fossils have been found in regions known to be near the poles during the Late Cretaceous, while relatively few fossils of nonendothermic marine reptiles have been found in those locations.

D. During the Late Cretaceous, seawater temperatures were likely higher throughout mosasaurs’ range, including near the poles, than seawater temperatures at those same latitudes are today.

This one likely seems complicated, but it’s just a matter of applying our evidence and conclusion method to a slightly different question. Do that, and you’ll be able to eliminate the wrong answer options because they’re inconsistent with the evidence and/or conclusion!

Let’s sum up the evidence again:

Mosasaurs were large marine animals that lived in the Late Cretaceous.
Oxygen-18 isotopes suggest mosasaurs were endothermic.

Summed up, that’s really our only evidence. The difference is we now have a conclusion/claim to think about as well:

The team claims endothermy would have allowed mosasaurs to include relatively cold Polar regions in their range.

It’s important to note that this isn’t evidence: it’s a conclusion/claim/argument/etc. that the team is making based on the evidence.

Hint: Don’t get hung up on the science words/terms: you don’t need to know anything beyond what’s in the text.

The question asks us to “support” their claim. All that means is that we need to pick an answer that is consistent with all the evidence and with their claim. In other words, something that makes their conclusion more likely to be true.

Let’s take a look at the answer choices:

Answer option A does not make it more likely that their claim is true. It’s irrelevant: we don’t care, in this case, about these other, non endothermic marine reptiles.
Answer option B is inconsistent with the claim. Tricky, but think about it: the claim is that the mosasaurs could survive in the polar regions because they were endothermic. If there are equal numbers of endothermic and non-endothermic animals at the poles, then that would suggest being endothermic has nothing to do with Polar survival.
Aha! Now answer option C is the opposite, and is exactly what we need. It’s consistent with the evidence and the claim: if mosasaurs were found at the pole but non-endothermic animals were not, then being endothermic would seem to be what allowed the mosasaurs to survive at the poles.
The “D” must stand for “dud:” answer option D is irrelevant, since we don’t care about current sea temperatures. They’ve got nothing to do with mosasaur survival at the poles!

Once again, we were able to take a brutally difficult, dense question and break it down. Let’s recap:

When the question presents you with a claim and asks you about “supporting,” “weakening,” “undermining,” or “bolstering” it, here’s what you do:

Identify the claim/argument/conclusion/hypothesis
- Remember: this is not a fact or evidence. This is what someone is arguing or trying to prove.
Identify all the facts/evidence.
Pick the answer option that is consistent with the evidence and (depending on the question) undermines or supports the claim.

SAT Reading Question Example 3

Let’s try another question from the “Command of Evidence” category.

In 1534 CE, King Henry VIII of England split with the Catholic Church and declared himself head of the Church of England, in part because Pope Clement VII refused to annul his marriage to Catherine of Aragon. Two years later, Henry VIII introduced a policy titled the Dissolution of the Monasteries that by 1540 had resulted in the closure of all Catholic monasteries in England and the confiscation of their estates. Some historians assert that the enactment of the policy was primarily motivated by perceived financial opportunities.

Which quotation from a scholarly article best supports the assertion of the historians mentioned in the text?

A. “At the time of the Dissolution of the Monasteries, about 2 percent of the adult male population of England were monks; by 1690, the proportion of the adult male population who were monks was less than 1 percent.”

B. “A contemporary description of the Dissolution of the Monasteries, Michael Sherbrook’s Falle of the Religious Howses, recounts witness testimony that monks were allowed to keep the contents of their cells and that the monastery timber was purchased by local yeomen.”

C. “In 1535, the year before enacting the Dissolution of the Monasteries, Henry commissioned a survey of the value of church holdings in England—the work, performed by sheriffs, bishops, and magistrates, began that January and was swiftly completed by the summer.”

D. “The October 1536 revolt known as the Pilgrimage of Grace had several economic motives: high food prices due to a poor harvest the prior year; the Dissolution of the Monasteries, which closed reliable sources of food and shelter for many; and rents and taxes throughout Northern England that were not merely high but predatory.”

Source: SAT Educator Question Bank

The same method applies here: start by gathering the evidence, then compare the evidence to the claim.

Based on the passage, what do we know?

Henry VIII split with the Catholic Church.
Then he closed the monasteries in England.
This involved confiscating the monasteries’ estates.

And we have a claim to consider:

Some historians think Henry’s policy was motivated by money.

The question asks for something that supports the claim, so we’re looking for something that matches both the evidence and the claim.

Answer option A is consistent with the evidence, but it doesn’t have much to do with the claim — it’s irrelevant. We know that the number of monks in England went down, since Henry closed the monasteries, but that’s irrelevant to the claim about Henry’s motivations.
Answer option B could very mildly weaken the claim, since it points out that monks could keep the contents of their cells. But the claim is about monasteries’ estates, not the relatively few possessions that monks had in their personal rooms. Let’s table B and see if something better comes along.
Answer option C notes that just a year before Henry dissolved the monasteries, he ordered a record of all their possessions. Then, conveniently, he seized all those holdings. This is pretty suspicious behavior, and it’s consistent with both the evidence and the claim: if Henry was so interested in knowing how rich the monasteries were, it seems likely that shutting them down had something to do with financial gain.
Answer option D is irrelevant. Worse, it’s confusing: this option mentions a result of the Dissolution of the Monasteries, but we’re talking about a cause.

By keeping both the evidence and the claim in mind, you can narrow it down to just one possible answer.

Hardest SAT Reading Questions Summary

Let’s recap. The hardest part of the SAT Reading & Writing section for most students will be what College Board calls “Inference” and “Command of Evidence” questions.

We really don’t like those terms because they don’t capture what’s actually being tested. Instead, we encourage you to think of them as Logical Reasoning questions. They test your ability to interpret, weaken, and support logical, evidence-based arguments.

How do you recognize these question types? There are a few key giveaways:

Any question that asks you what “logically completes” a phrase or passage.
Any question that uses language about “weakening” or “supporting” a conclusion, claim, hypothesis, or argument.
Any question that asks you to compare visual data (a chart or graph) with a text passage.

How do you eliminate incorrect answer choices and get to the correct one?

Look for logical consistency! The right answer will align with the evidence and either support or contradict the conclusion (depending on the question). The wrong answers will not properly match up with the evidence and/or the conclusion.

All three of these question types will come up on your SAT. No doubt about it. The only question is whether you’ll be flustered by them (like most students) or be ready for them.

Of course, these question types–while the most difficult–are only a small part of the puzzle. Getting a high or perfect score on the SAT requires mastering every part of the test. If you’re serious about aiming for that goal, we recommend you spend some time reading our detailed breakdowns of the digital SAT.
