Testing time is 2 hours 14 minutes: two 32-minute Reading and Writing modules and two 35-minute Math modules. Add the single 10-minute break and the clock inside the test runs 2 hours 24 minutes. With check-in and instructions, plan on being at the test center from about 7:45 a.m. until roughly 11 a.m. for standard time.

Can I take the digital SAT on my phone or personal Chromebook?

No. Bluebook does not run on a phone, and College Board states you cannot test on a personal Chromebook. Only school-managed Chromebooks are supported, alongside Windows laptops and tablets, Macs and iPads.

Do I need to bring a calculator to the SAT?

Not necessarily. Bluebook has a built-in Desmos calculator with graphing and scientific modes that you can use for the entire Math section. Bringing an approved non-CAS handheld calculator is allowed and gives you a fallback if you prefer one.

How many breaks are there on the SAT?

One. A single 10-minute break sits between the Reading and Writing section and the Math section. There is no break between the two modules inside a section.

Are all 98 SAT questions scored?

No. Each of the four modules contains exactly 2 unscored pretest questions, so 90 of the 98 questions count. Pretest items are placed randomly and look identical to scored ones, which is why guessing which questions do not count is a waste of time.

How Long Is the SAT? Test Day Timing and Rules

Testing time on the digital SAT is 2 hours 14 minutes. That is two 32-minute Reading and Writing modules and two 35-minute Math modules. Add the one 10-minute break between the sections and the clock inside the test runs 2 hours 24 minutes.

Total time at the test center is longer. Check-in starts at 7:45 a.m. and doors close at 8 a.m., testing begins somewhere between 8:15 and 8:30, and standard-time testing ends between 10:45 and 11 a.m. according to College Board’s test day page. Budget the whole morning.

The timing, module by module

Segment	Questions	Time
Reading and Writing, module 1	27	32 min
Reading and Writing, module 2	27	32 min
Break		10 min
Math, module 1	22	35 min
Math, module 2	22	35 min
Total	98	2 h 24 min

Each module is timed separately. You can move freely between questions inside a module, but once you advance to module 2 you cannot go back to module 1. That is the rule most students discover too late, so treat the end of each module as final.

Module 2 is adaptive. Your performance on module 1 routes you to either a lower-difficulty or higher-difficulty second module, and this happens within a section only. Reading and Writing routes independently of Math. There is no published threshold for how many questions it takes to reach the harder module, and anyone quoting you a specific number is guessing.

Only 90 of the 98 questions are scored

Every module contains exactly 2 unscored pretest questions. College Board’s test specifications overview states it plainly for each module: “25 operational questions and 2 pretest questions” in Reading and Writing, “20 operational questions and 2 pretest questions” in Math.

That leaves 50 scored Reading and Writing questions and 40 scored Math questions. The pretest items are placed randomly and are indistinguishable from the ones that count, so there is no way to identify them and no benefit in trying.

The test day clock

Time	What happens
7:15 a.m.	Arrival time if you are borrowing a device from College Board (30 minutes early)
7:45 a.m.	All students check into the test center
8:00 a.m.	Test center doors close
8:15-8:30 a.m.	Testing begins after seating, sign-in and the start code
10:45-11:00 a.m.	Standard-time testing ends

During check-in the proctor assigns your seat, you connect to the test center Wi-Fi, open Bluebook and receive a start code. Proctors answer questions about procedure only, never about test content.

What Bluebook needs from your device

Bluebook is the application the test runs in. It has to be installed and working before you arrive.

Device	Minimum OS	Free space
Windows laptop or tablet	Windows 11 24H2	1 GB
Mac	macOS 15	1 GB
iPad	iPadOS 18	250 MB
Chromebook (school-managed only)	ChromeOS 144	1 GB

Two exclusions matter. College Board states you cannot test on a personal Chromebook or a phone. Windows S mode and Windows 11 SE are also unsupported, which quietly rules out a fair number of cheap school laptops.

Your device has to hold a charge for roughly three hours. Test centers are not required to provide an outlet, so a power bank is worth bringing even though it is optional.

Exam setup before test day

Bluebook’s own sequence is specific about timing. Install the app and run “Test Your Device” at least 30 days out, and practice with the app on the same device you will test on. Then in the 5 days before test day, reopen Bluebook so it pulls the latest version, check that your personal details match your ID, and complete exam setup, which generates your admission ticket.

Run “Test Your Device” once more on the morning of the test to confirm you still have free space.

What to bring

Required:

Your fully charged testing device with Bluebook installed and exam setup completed
Your up-to-date admission ticket from Bluebook (printed is preferred)
Acceptable photo ID, a physical document, not a photo on a phone
Pens or pencils for scratch work
Your College Board username and password

Optional and allowed:

A power cord or portable charger
An approved calculator
An external mouse, and an external keyboard if you are testing on a tablet
A watch without an audible alarm
A backup testing device
Snacks and drinks for the break, stored in a bag

Scratch paper is supplied by the testing staff and collected at the end. Do not bring your own.

What is banned

The testing rules prohibit phones, smartwatches, fitness trackers, cameras and any other electronic or communication device beyond your approved testing equipment. The list also covers smart glasses and any eyewear that provides internet or AI access.

Stylus pens, Apple Pencils and other electronic writing instruments are prohibited, which surprises iPad testers. So are watches that beep or have a timer.

Prohibited items cannot be accessed during breaks either, and you must follow the test center’s process for storing your phone. Taking your testing device out of the room during the test or the break is not allowed.

The break

There is exactly one break, 10 minutes, between the Reading and Writing section and Math. There is no break between the two modules inside a section, so a 32-minute Reading and Writing module runs straight into the next one.

You can eat and drink during the break in the designated area, but not at your desk and not from a stored bag you are not permitted to open. You cannot check your phone.

The calculator and the reference sheet

A calculator is permitted for the entire Math section, both modules. It is not permitted during Reading and Writing, where it has to stay under your desk.

Bluebook has a built-in Desmos calculator with a graphing mode and a scientific mode, and you can toggle between them at any point during Math. If you prefer a handheld, it has to be non-CAS. Calculators with a computer algebra system are prohibited, including the Casio ClassPad series, HP Prime and TI-Nspire CAS. Also banned: anything with a QWERTY keyboard, wireless connectivity, a camera or recording capability, plus laptops, tablets and phone calculator apps.

A reference sheet with commonly used formulas appears on every test with math questions, built into Bluebook. You do not need to memorize the formulas it contains, though knowing them saves you the clicks.

The other tools inside Bluebook

Annotation, to highlight text in a question or leave yourself a note
Mark for review, a bookmark flag on any question you want to return to inside the current module
Timer, showing time remaining in the module, which you can hide until the 5-minute alert
Line reader, to isolate a narrow band of text
Option eliminator, to cross out answer choices you have ruled out

Practice with these in Bluebook before test day rather than meeting them cold.

After you submit

Answers are submitted automatically when the test ends, with a resubmission window available through the following day if the connection fails. You will not see a score at the test center.

Score release for fall 2026 weekend dates runs exactly 13 days after test day, and the SAT score release dates guide has the full calendar.

Because the digital SAT is scored with Item Response Theory rather than a raw-score lookup, there is no table that turns “I missed 6” into a scaled score. College Board states directly that two students with the same number of correct answers can receive different scale scores. Our digital SAT score calculator explains what can and cannot be estimated, and the Math and Reading and Writing tools handle each section separately. The methodology page sets out exactly where every figure on this site comes from.
