What is the digital SAT?
The digital SAT replaced the old paper test for most students. You take it on a computer through the College Board's Bluebook app rather than with a pencil and booklet. It is shorter than the paper version, runs about two hours and fourteen minutes of testing time, and is scored on the same familiar 400 to 1600 scale. It is also adaptive, which means the test adjusts to how you are doing as you go.
How it is structured
There are two sections, Reading and Writing first, then Math. Each section is split into two equal-length parts called modules. Reading and Writing has two modules of 27 questions with 32 minutes each, so 54 questions in about 64 minutes. Math has two modules of 22 questions with 35 minutes each, so 44 questions in about 70 minutes. That is 98 questions in total, with a short break between the two sections.

What "adaptive" actually means
Everyone gets the same first module in each section. Your performance on that first module decides whether the second module is a harder set or an easier set. The harder second module unlocks the top of the score range; the easier one caps the score lower. This is why two students who answer the same number of questions correctly can still earn different scaled scores, and it is the single biggest thing that surprises people about the new format. You can see how the routing affects scores with the digital SAT score calculator.
Module 1
everyone gets a mixed set
Harder Module 2
did well → unlocks the highest scores
Easier Module 2
struggled → gentler set, lower score ceiling
What is on each section
Reading and Writing uses short passages, each with a single question, spanning four content areas: Information and Ideas, Craft and Structure, Expression of Ideas, and Standard English Conventions. The passages are brief, so the test rewards careful reading and grammar precision over stamina.
Math covers Algebra, Advanced Math, Problem-Solving and Data Analysis, and Geometry and Trigonometry. An on-screen graphing calculator is available for the entire Math section, and some questions are "student-produced responses" where you type the answer instead of choosing from options.
How it is scored
Each section is scored from 200 to 800, and the two add up to your 400 to 1600 total. Your raw score, the number of questions you got right, is converted to the scaled score, and because there is no penalty for wrong answers you should always put down a best guess rather than leave anything blank. The adaptive routing then shapes the top of the range you can reach. To turn a practice raw score into an estimated scaled score, use the score calculator.
How to prepare for it
Take full-length practice tests in conditions close to the real thing, get familiar with the digital tools before test day, and focus your studying on the specific skills where you lose the most points using spaced, active practice rather than passive review.
