Deep Dive on the 4 Digital SAT Practice Tests

The digital SAT debuted in March 2024, and since then we’ve researched every official exam, prepared thousands of students to earn top SAT scores, and spoken directly with College Board test developers. Over the past 2 years, we’ve learned a lot about this cryptic test, including how the adaptive format affects students and how the test is scored (it’s probably not what you’d expect!). Here’s our in-depth take on what students and educators need to know about the test.

Easier and Harder Adaptive Modules

One of the main reasons the College Board shifted the SAT to a fully digital format was their desire to use an adaptive test structure. Depending on how a student performs on the first portions (called “modules”) of the test, the next portions will adjust in difficulty, shifting to easier or harder content. By focusing on questions that target each student’s ability level, the SAT is able to maintain its scoring accuracy while reducing the number of questions and testing length.

There is a pronounced difference in average difficulty level between the SAT’s Lower (easier) and Higher (harder) adaptive modules. Students who find themselves on easy street have most likely landed in the Lower module, so it may ironically be a problem if the SAT doesn’t feel like a challenge! By our estimate, about 3/4 of the questions on the Lower Math module are on the easier half of the difficulty scale, compared to only about 1/4 of the questions on the Higher module. Below are the general difficulty ratings of questions in the baseline, Lower, and Higher SAT modules. These present very different mountains for students to climb.

Harder Adaptive Math Module

Note that every module will have easy, medium, and hard items, but the ratios are quite different for the Lower and Higher modules.

Scoring

The College Board has kept their SAT scoring algorithm a mystery, with no official documentation on the specifics of how points are earned. Students might ask, “How many correct answers do I need to get a 650? A 720?” When it comes to classical testing, i.e., the older versions of the SAT, the total number correct will correspond directly to a scaled score. When it comes to adaptive testing, scoring is much more nuanced, as individual questions in particular sections are worth different amounts. The varied impact of different questions is called weighting. These differences in question weights affect your scaled scores, and they are also factors in determining whether you get into the Higher or Lower modules on the test. In short, some questions are worth more than others are.

Overall, the questions that appear in the Higher modules are worth more than those in the Lower modules. Therefore, there’s a limit to how many points a student can earn if they get routed into the Lower modules. Do students need to get into the Higher modules to earn their goal scores? Not necessarily. Students who perform exceptionally well on the Lower module can still earn up to a 600 on the Math or Reading & Writing section. Further, students who struggle on the Higher module may score as low as a 450. About half of all students fall in this 450-600 range, where it doesn’t matter if they get into the Lower or Higher modules; though the difficulty of the modules may change, the scoring will adapt and still provide a score that accurately measures the students’ abilities. If a student is aiming for a score above 600, they must get into the Higher module, which requires answering about 2/3 of the questions correctly in the first (”baseline”) module.

For a practical look at SAT’s scoring system, consider the following scores on the first official Reading & Writing test:

Reading & Writing Scoring Digital Test 1

The top two students were routed to the Higher module (green highlight) while the bottom student was routed to the Lower module (blue highlight). The student who was routed to the easier module answered 43 items correctly and attained a scaled score of 560, while the student who was routed to the harder module and answered 30 items correctly also attained a 560. These students demonstrated similar overall ability levels, but they had a very different testing experience.

In a similar light, here are some sample scores from the Math section:

Math Scoring Digital Test 1

Notice that the student who attained a total of 15 of 44 total correct answers attained a 460, though they didn’t answer any questions correctly in the Higher module, while the student who attained 25 total correct answers and was routed to the Lower module section needed to answer more questions correctly to earn the same score. Also, the two students with 35 total correct answers got very different scores (100 points apart), as the student in the Higher module correctly answered questions that were worth more points. For the digital SAT, the number of correct answers is not as instructive as it has been in the past.

Since the initial release of official digital SAT practice tests on the Bluebook app, the College Board has updated tests 1–3, recycling most of their content to create tests 8–10 (along with the addition of more challenging questions, thus making these practice tests more representative of official tests). These updates have improved the tests’ scoring accuracy, but the score weighting system outlined above has remained the same. Likewise, we have made continual updates to our own SAT materials, and our proprietary SAT practice tests have consistently outperformed the official practice tests in scoring accuracy (further improved by our detailed score reports, offering more actionable data than the College Board’s vague reports)!

Question Weighting

In addition to the Higher or Lower modules, there are other factors that affect how much questions are worth on the SAT. In the Digital SAT Assessment Framework, the College Board mentions that “the use of item response theory (IRT) and ability estimation will provide the basis for calculating scale scores.” We spoke with the lead psychometrician at College Board, Tom Proctor, who gave us more specifics about this complex system, which we have corroborated with many hours of independent research. The most surprising factor in the SAT’s scoring system is that, within each module, easy questions often have a greater scoring impact than harder questions do.

On the first official SAT practice test, if you only missed #25 in the Higher module of Reading & Writing, you would get a 780. On the same module of the same test, if you only missed #23, you would get a 750. These questions even tested the same concept, but one was worth more than twice as much as the other. Why the difference? #23 was worth more because it was the easier question.

This weighting may seem counterintuitive, but it is based on how well these questions indicate test-takers’ abilities. Put simply, high-scoring students usually get easy questions right, so missing an easy question means you’re less likely to be a high-scoring student. Further, even high-scoring students are likely to miss the hardest SAT questions, so those questions have a smaller impact on scores. Additionally, we have found that the Math section’s Student-Produced Responses (those questions that ask students to enter their own answer rather than selecting a provided answer choice) are also worth more than most other questions. For students preparing for the SAT, it’s essential that they identify patterns of careless mistakes on practice tests so they don’t make errors on easy problems on the big test day. Also, never skip a Student-Produced Response question, even if they are intimidating and time-consuming.

Insights on the Math Section

With only 22 problems per module, the SAT Math section doesn’t leave room for mistakes. Fortunately, the majority of the content is focused in specific content areas (primarily algebra), and the digital calculator is a massive help.

Algebra Skills Are Essential

At least 70% of the SAT Math section is focused on algebra skills, with half of those questions testing Algebra I concepts (such as inequalities and systems of equations) and half testing Algebra II concepts (such as quadratics). For most students, mastering all of these skills is the key to earning a competitive SAT Math score. If a student is aiming for a top Math score, they should also dedicate some prep time to the few geometry and trigonometry concepts on the SAT (these only appear 5-7 times per test, which is relatively low, but it can make a significant difference!).

Desmos is a Game-Changer

The powerful Desmos graphing calculator is baked into the official Bluebook testing app. As noted earlier, much of the SAT Math section is focused on algebra skills; fortunately, most of these algebra questions can be quickly solved with the use of a graphing calculator. When students learn how equations are represented in graphs, Desmos offers a significant score boost.

Insights on the Reading & Writing Section

Reading is short but tough. With the digital SAT update came a shift to shorter passages, but they are not necessarily easier passages. The reading level on the practice tests is as high as, if not higher than, prior versions of the SAT, and the questions often require a deeper level of consideration. For many students, the primary barrier to top SAT Reading & Writing scores is needing to practice logical analysis of complex ideas. This practice involves making supportable inferences, recognizing when assumptions aren’t absolute, and identifying causative connections.

Switching to a new topic, voice, and style with every question requires mental agility. Some students may prefer the shorter passage because they don’t require as much sustained focus, but others may find it tiring. Counterbalancing this, the predictable grouping of questions by type (i.e., all vocabulary at once, followed by all craft and structure questions at once) does allow a student to get into a particular problem-solving mindset for a stretch of time.

Here are some additional notable aspects of the Reading & Writing section:

• Decreased emphasis on grammar overall, but an increased emphasis on logical transitions
• Increased emphasis on vocabulary, which may be tough for some ELL students
• Elimination of idiom questions, which is good for ELL students
• Greater diversity of ideas and tones with more and smaller passages
• Question types are grouped and come in the same order every time
• Significant increase in humanities passages, surveys of artists/musicians
• Poetry is new, but relatively rare: we’ve seen poems from Shakespeare, Walt Whitman, all early 1900s or earlier public-domain poets

Vocabulary, But Not “SAT Vocab”

The increased focus on vocabulary in context does not mean a return to flashcards. Unlike previous versions of the test, the digital SAT doesn’t regularly test a small set of words. Instead, official exams have tested a wide range of vocabulary with few repeats. Students must pay attention to how words are used in different contexts, a skill that is best built through logical analysis and habitual reading.

Closing Thoughts

The digital SAT is a unique test, and each student will need their own particular plan for how they can efficiently reach their highest potential scores.
