How the digital SAT actually works
Shorter than the paper test, adaptive between modules, and sat on a laptop in the College Board's own app. Here is the structure, and what each part of it means for how you prepare.
The digital SAT is a 2 hour 14 minute test of 98 questions, split into two sections of two modules each. It is taken in the College Board's Bluebook application, and it is multistage adaptive: how you perform in the first module of a section determines the difficulty of the second.
The structure
| Section | Modules | Questions | Time | Per question |
|---|---|---|---|---|
| Reading and Writing | 2 | 27 each (54) | 32 min each (64) | about 71 seconds |
| Math | 2 | 22 each (44) | 35 min each (70) | about 95 seconds |
A 10 minute break falls between the two sections. Scores run 200 to 800 for each section, so 400 to 1600 in total.
What "adaptive" means here
It does not adapt question by question. Both modules of a section are fixed once they begin. What adapts is the second module: do well in module 1 and module 2 is drawn from harder material; do poorly and it is drawn from easier material.
This has a consequence students routinely miss. The first module matters more than the second, because it decides which scoring range you are playing in. A strong first module and a mediocre second usually beats the reverse.
Reading and Writing
Each question has its own short passage — usually 25 to 150 words. There are no long passages with five questions hanging off them. Questions are grouped loosely by type and rise in difficulty within each group, which is why the last question before a topic change is often harder than the one after it.
The four content areas are Information and Ideas, Craft and Structure, Expression of Ideas, and Standard English Conventions.
Math
Roughly three quarters multiple choice, one quarter student-produced response — the ones where you type the answer rather than pick it. The Desmos graphing calculator is built into the app and available for the whole section, which changes which questions are worth solving algebraically and which are worth graphing.
The tools you get, and which are worth using
- Mark for Review — flag and return. Useful, and underused.
- Answer eliminator — strike out choices. The single most useful button on the screen for Reading and Writing.
- Highlight and annotate — mark the passage and leave a note.
- The Desmos calculator — worth real practice before test day. Students who meet it for the first time in the exam lose time to it rather than saving time with it.
- The countdown timer — can be hidden, and for some students should be.
What changed from the paper SAT
- About an hour shorter
- Shorter passages, one question each
- Calculator allowed on all of Math, not half of it
- Adaptive between modules, so no two students sit quite the same test
- You cannot go back to module 1 once module 2 begins
Questions people ask
- How long is the digital SAT?
- 2 hours and 14 minutes of testing — 64 minutes for Reading and Writing, 70 for Math — plus a 10 minute break between sections.
- Can you go back to previous questions?
- Within a module, yes, freely. Once a module ends you cannot return to it.
- Is the second module always harder?
- No. It is harder if you did well in the first module and easier if you did not. Being given an easier second module caps the score you can reach.
