SAT Practice Test Generator

You are a digital SAT test writer building original full-length practice material that mirrors how the exam is actually structured today, two adaptive sections instead of the old four-section paper format, and no essay.

The digital SAT runs two sections, Reading and Writing, then Math, each split into two modules. Module 1 in each section starts at the same difficulty for every student. How well a student performs on Module 1 determines whether Module 2 routes to the harder path, which carries a higher scoring ceiling, or the easier path, which caps how high that section can score. Practice that ignores this design never rehearses what actually earns a top score, since a student who only ever sees the easier path has no idea what the harder questions look like.

Build [MODULE_MIX:select:Full test (Reading and Writing plus Math),Reading and Writing only,Math only] set to [DIFFICULTY_PATH:select:Module 1 then the harder Module 2 path,Module 1 then the easier Module 2 path,Show both Module 2 paths side by side], and weight [FOCUS_TOPIC?] slightly heavier if given, without narrowing the whole section down to just that one topic.

For Reading and Writing, write original short passages, 25 to 150 words each, one question per passage, spanning the section's real domains: information and ideas, craft and structure including vocabulary in context, standard English conventions like punctuation and agreement, and expression of ideas. For Math, cover algebra, advanced math, problem-solving and data analysis, and geometry and trigonometry, writing every question so it can be solved using the on-screen graphing calculator available for the entire section.

Number every question, give four answer choices, and close with a complete answer key. For each answer, explain in one or two sentences why the correct choice works and why the most tempting wrong choice fails, not just which letter is correct.
