Understand materials, judgments & learning records

Sources and review status are explained per task

The preview library retains 100 materials, organized as 80 practice and 20 reserved items; this does not mean all content is approved for release. Formal assignments currently offer 9 individually accepted items: 6 practice and 3 reserved checks. Image authors, original pages and licenses are listed with each task.

Original texts and answers are fictional teaching scenarios. Image references derive from public dataset annotations scaled to the display dimensions. Materials passed structural, citation and AI checks; this is not independent human expert review by this project. The human-reviewed material count remains 0 out of 100. Interpret each task using its quality status and version.

The first batch was accepted by owner-authorized Astra AI; the actual human review count remains 0. Approval binds exact items, versions and content bytes. Unreviewed, deferred, withdrawn or changed versions do not inherit approval. Only the original 12 mock interview questions were accepted for open practice, reference and personal self-assessment; the 20 added company-related questions are outside this approval.Human review of one learner submission does not mean the entire underlying material has passed quality acceptance. Material checking, grading calibration and submission review are separate activities.

Results describe this task; revisions and independent judgment are recorded separately

Image results check object counts and box coverage; text results check labels and quoted evidence; AI evaluation checks individual ratings, overall comparison and evidence. Boundary tolerances and content judgments still need human checking and calibration. Results do not establish validated learning effectiveness. Free-text explanations are stored for review, not automatically approved for meaning.

First submissions, revisions after feedback and new-material checks are retained separately. Meeting structured criteria once does not establish job readiness or certification. New material may use different rules; reread the objective and requirements.

Held-out material is assigned using source-exposure records known to the server: within the valid browser session before account connection, and within known account-owned records after linking. Public photos may appear elsewhere. Changing devices or clearing credentials does not prove a person has never seen them.

Drafts can be restored; final submissions are locked

The workbench saves annotations, choices, evidence quotes, short reasons, uncertainty reasons, save times and material versions. It also retains exposure, linked revisions, results and authorized human decisions to restore work and distinguish learning evidence.

“Draft saved to server” means the current changes received save confirmation. Unconfirmed changes may exist only on the page. During network or draft conflicts, export the current answer before retrying or reloading. A revision creates a new attempt after submission is locked; it does not overwrite the original judgment.

Without an account, records are isolated by browser session. After a verified identity connects, new attempts belong to the account. Previous browser records require your explicit confirmation to link. The account page supports session revocation, JSON export and deletion of the account and its records by typing DELETE and obtaining server confirmation.

Browser session credentials last 30 days. Expired or lost credentials do not mean database records are deleted. Recovery after anonymous credential loss, automatic retention periods and full hosted recovery still require operational configuration and verification. Learn more inPrivacy & data processing。

When uncertain, retain evidence and state the next step

After choosing “Needs human confirmation,” explain what is known, what is missing and what cannot be judged. Submission keeps an identifier and enters pending review. Waiting does not automatically turn it into a passing result.

Only configured authorized reviewers can access the controlled workspace. Case assignments govern access to answers and references and allow evidence-based human decisions. Original submissions and automatic results remain. No assignment or response time is promised.

For a review or a suspected reference issue, give the submission ID, material version and specific concern to the person who invited you, or raise it in your project communication. You can continue other tasks meanwhile.
