The short answer
PeakSAT uses different checks for different materials. Public worked examples are checked against their stated prompts. App practice draws from questions marked eligible in our bank. Newly generated drills pass format, near-copy and independent-answer checks before use. This page explains those checks and how to interpret independent practice estimates.

What “checked questions” means
In our question bank, checked is an eligibility flag used by practice selection. A usable question needs an answer and appropriate content for the requested task. The flag records practice eligibility rather than independent human-review provenance. Question-bank totals describe the available inventory; the questions delivered depend on the activity and its selection rules.
A dated question-bank snapshot
On October 10, 2026, our read-only inventory check found 6,154 bank records and 5,857 eligible for the current practice selector, including 332 numeric-response questions across a 29-topic catalog. The selector requires the checked flag and a recorded correct answer and excludes unavailable legacy image references. This dated inventory supports the “5,800+” practice-bank description.
How generated drills are checked
Google AI creates original drills for a selected SAT skill. The pipeline validates the response format, passage context, distinct answer choices and numeric-answer rules. A conservative text-similarity check rejects close copies. A separate Google AI context solves the question without seeing the proposed answer or explanation and checks ambiguity, scope and answer agreement. Failed items are quarantined instead of delivered as approved drills. These automated checks reduce errors; they cannot prove that an item is error-free.
Public examples teach a specific move
Our public examples are original teaching problems rather than official College Board questions. Each solution explains the reasoning and, for multiple-choice problems, why the other choices fail. Difficulty labels describe intended demand, not psychometric calibration. Use a fresh transfer problem to check understanding rather than treating a remembered answer as mastery.
Practice estimates and official scores
PeakSAT assessment results are independent practice estimates, not equated official SAT scores. Official digital SAT scoring uses more than a simple wrong-answer count. Imported official or Bluebook section scores retain their source and require confirmation. The app uses those sections to guide planning and question-level practice to identify skills that need work.
AI help is study assistance
The question tutor uses the selected problem and the work you share to offer hints and steps. Full explanations and narrated walkthroughs require an attempted question. Google AI can still misunderstand a prompt or make a calculation error. Compare its reasoning with the question and reference solution; report a conflict rather than memorizing an unsupported result.
Study evidence you can inspect
Public worked solutions show the method, answer checks and reasoning behind each example. In the app, use fresh practice attempts, mistake review and the recorded source of each score to assess your next study step. Compare progress under similar conditions so the evidence helps you choose what to practice.
Help us correct a problem
For a public page, email nicole@peaksat.com with the URL, the exact issue and your reasoning. For an app question, use the question-report workflow and include the issue that needs review. A material correction updates the affected public page’s review date. We keep SAT format, scoring and policy guidance linked to primary sources so readers can check changing rules.
