How unit tests work

  • Focused on a single AP unit, between a single-topic quiz and the full diagnostic.
  • 4 variations per unit — pick a fresh variation any time you retake.
  • Roughly 90 seconds per question — the same pacing as the AP exam.
  • You'll get a unit-level score, recommended topics to review, and a question-by-question explanation.

About the SAT exam

The SAT is a fully digital, multistage-adaptive college admissions test administered by College Board through the Bluebook application. It measures the reading, writing, and math skills colleges consider central to first-year readiness, and most four-year universities accept it (often interchangeably with the ACT) for admissions and merit-scholarship decisions. The exam is built around two sections. Reading and Writing blends short passages with questions on main ideas, evidence, vocabulary in context, sentence boundaries, transitions, and standard English conventions; every question is tied to a single short passage rather than the long reading blocks of the paper era. The Math section spans algebra, problem solving and data analysis, advanced math (including quadratics and nonlinear functions), and a small amount of geometry and trigonometry, with an embedded Desmos graphing calculator available throughout. Each section is split into two modules, and the difficulty of your second module is set by how you perform on the first, so early accuracy directly affects the ceiling of your score. Because scoring uses item response theory rather than a simple count of correct answers, harder questions answered correctly carry more weight. Students typically struggle with pacing under the adaptive format, with the dense, inference-heavy short reading passages, and with the algebra-heavy no-calculator-style reasoning even though a calculator is allowed. Effective preparation centers on official Bluebook practice tests, targeted review of grammar rules and core algebra, and building comfort with the Desmos tool. Strong SAT performance can meaningfully expand admissions options and unlock scholarship money.

Exam structure

Two sections, each in two adaptive modules: Reading & Writing (54 questions, two 32-minute modules) and Math (44 questions, two 35-minute modules). Total testing time is about 2 hours 14 minutes plus a 10-minute break; a few unscored pretest questions are embedded.

Scoring

Each section is scored 200-800 via item response theory and the two combine into a total score of 400-1600.

Common mistakes

  • Treating the first module casually — weak first-module performance routes you to an easier, lower-ceiling second module and caps your score.
  • Over-reading the short Reading & Writing passages instead of going straight to the question stem and the specific evidence it asks about.
  • Forgetting that every question is worth the same to you in the moment, so burning minutes on one hard problem starves easier points later.
  • Underusing the built-in Desmos graphing calculator on algebra and function questions where graphing is faster than hand computation.
  • Misapplying comma, semicolon, and colon rules on the high-frequency sentence-boundary and punctuation questions.
