Practice with a clear provenance

Original practice content

Every bundled question in this version is marked CLEARMARK_ORIGINAL. These are ClearMark-created practice questions, not official Cambridge questions, past papers or mark schemes.

The library now covers Accounting 0452, Enterprise 0454, Business Studies 0450, Economics 0455, First Language English 0500, Mathematics 0580, Biology 0610, Chemistry 0620, Physics 0625, Computer Science 0478 and ICT 0417. Each newly added subject has a ten-question topic bank, and all eleven subjects have a curated six-question ClearMark Mini Mock.

Topic coverage is syllabus-informed, but each Mini Mock is a compact skills set rather than a replica of an official paper. Subject codes and syllabuses can change between examination years, so learners should confirm the syllabus for their own exam series.

Any future official-paper support would use private, authorised sources with appropriate access controls; it would not republish restricted material publicly.

What this version deliberately excludes

• Public scraping or republishing of restricted paper content
• Downloadable Cambridge archives or background PDF parsing
• Examiner-equivalence claims or grade predictions
• Payment flows or targeting learners under 13

Feedback boundaries

Objective and calculation items use versioned deterministic ClearMark rules and are never sent to an AI model. Enterprise and other open-response planners check configured reasoning structure and case or source use; that is practice guidance, not an official mark. Longer answers benefit from teacher or second review.

An eligible adult user may separately opt in to short AI coaching when submitting an Enterprise response. AI prose cannot change structure evidence, mistakes, retests, mastery or the second-review route.

Minimum data

The homepage and sign-in are publicly reachable, but learning records are not public. Every protected page and API request requires a signed-in identity with an active ClearMark access grant. The owner can suspend that grant while preserving the learner’s records.

ClearMark is designed for learners aged 13+ and above the applicable age of digital consent. The Site uses a stable signed-in principal to keep attempts, mistakes, retests and mastery separate. It does not ask for a date of birth, address, phone number or school ID. Learner responses and feedback are not placed in operational telemetry.

AI coaching is off by default and limited to testers who confirm they are 18 or older. When selected, only the ClearMark-original Enterprise prompt, case, required reasoning stages and submitted planner text are sent to DeepSeek. ClearMark does not attach the signed-in account name, email, principal identifier, confidence, study history, mark-point mapping or any Accounting response.

ClearMark removes common email, phone, link, name and school-identifier patterns before transmission. Automated redaction can miss personal information, so the planner must not contain names, contact details, credentials or school identifiers.

Teacher access uses a server-verified role plus an active class relationship. Learners join with a hashed, expiring invite code and remain pending until the teacher approves a class-specific display label. A browser role switch cannot grant authority.

Teacher reports contain aggregate attempts, assignment completion, active mistake counts, due retest counts and topic mastery with evidence counts. They never contain raw student answers, question or source text, marking rules, mark-point mappings, detailed feedback or AI advisory prose.

ClearMark AI processing notice

This notice governs the optional AI feature. Its purpose is to return short reasoning advice on an eligible adult user’s Enterprise planner. The categories sent are the original practice question context and planner text; the recipient is DeepSeek. No AI output is used for deterministic marks, mistakes, retests or mastery.

DeepSeek states that data may be processed in China and handled under its retention and service-improvement practices. ClearMark cannot offer a request-level no-training guarantee. Leaving the option unticked withholds consent and keeps the complete deterministic check inside ClearMark. A completed external request cannot be withdrawn from transmission after submission.

Before granting learner roles, the operator must supply its users with an appropriate contact, lawful-basis, retention, rights and cross-border-transfer notice. DeepSeek’s document is provider reference material; it is not a substitute for the operator’s own notice.

Prototype runtime adaptations

• Enterprise keeps deterministic structure and case-evidence guidance authoritative. DeepSeek may add bounded advisory prose only when an eligible adult user opts in.
• Learners under 18 continue with the complete deterministic experience; ClearMark does not collect a date of birth or implement a guardian-consent workflow in v0.1.
• The teacher workspace is enabled through a verified server role and approved class memberships. Parent accounts and school-wide administration remain out of scope.
• The expanded original bank uses multiple choice, numeric workings, short text and guided reasoning planners. It does not reproduce official paper layouts.

Coursework boundary

Enterprise support is for generic planning and self-review. Assessed coursework must remain the candidate’s own work.
