AI can do their homework. It can't take their test.

• Course-shaped, not grade-shaped. High school runs on courses, so the practice does too: Algebra I, Geometry, Algebra II, and English I–IV — 17 course-bucketed skill families with adaptive levels.
• A readiness meter for a named exam. Each course shows one number, 0–100, weighted like the exam it points at — the Algebra I and English II end-of-course blueprints, and the SAT Reading & Writing pair for grades 11–12. Practice rounds draw questions in the exam's own proportions.
• A respectful register. The 9–12 surface drops the mascot, the confetti, and the cheer. Complete a round and it says what happened: 7 of 10, here's your score, fix your misses if you want.
• Real writing, really judged. Argument, analysis, and informative prompts at formal register — the performance-event half of the English EOCs — plus story prompts, all scored against named rubrics by an AI model (Anthropic's Claude) that picks from our fixed set of pre-written coaching lines. The student never sees text the model wrote. How Writing Coach handles answers.
• Find-my-level placement. A short course-aware diagnostic places a new student at their real working level, not at the bottom of a ladder.

• Transcript-ready mastery records. Every mastered skill is a dated, machine-verified record you can print into a homeschool portfolio or transcript file. We record mastery — we do not grant credit, and we say so plainly.
• The full parent dashboard, weekly digest, and printable reports — same as every paid AcornSmarts plan.
• Practice works offline (Writing Coach needs a connection), no ads, no tracking in the app, and the same privacy architecture as the rest of the app: see where student data goes.

We published the audit instead of a slogan. Every Kansas and Missouri high-school standard code is listed with the verdict our own adversarial audit gives it — FULL, PARTIAL, or NOT COVERED, with the gaps named as plainly as the coverage, and a playable live item beside the evidence wherever an item can be played (Writing Coach rows cannot be sampled). Since 25 Oct 2026, so is every Arizona content-standard code for Algebra I, Geometry, Algebra II and grades 9–12 ELA.
