Read-only by design
The application exposes GET pages only. It cannot submit answers, change learning records or access administrative actions.
Provenance and limits
Evidence methodology
This page explains how the review copy separates source evidence from presentation.
Dated snapshot
Production data is included only through an authorised export with a stated generation time and records-through date.
No inferred mastery
Study duration is not presented as proof of knowledge. Completion, recorded results and learning observations remain distinct.
Assisted study
ChatGPT-assisted time is reported only when the source system explicitly classified an interval as assisted study.
Terminology
Training papers are labelled “Practice Paper” or “Practice Papers”. Historical source identifiers remain available in provenance metadata without promotional or predictive claims.
Original system preserved
The live Study Exam Coach remains separate and unchanged. This copy does not share its writable database, logs or runtime state.
English derivatives
Translated materials are identified as English derivatives prepared for this review. Private originals and source mappings are retained. Translation does not change the recorded dates, scores or study activity.
Review status
Source-system quality checks are internal checks, not approval or endorsement by Imperial College London. A paper awaiting source quality review remains listed without exposing its held questions.

Snapshot-specific notes
- The initial learning-record export opened the production SQLite database with mode=ro, immutable=1 and query_only enabled; subsequent authorised paper-content export used normal read-only SQLite access.
- Only records explicitly associated with student key or student id 'tony' were considered.
- Known QA, smoke, browser automation, deployment-test and synthetic identifiers were excluded.
- Focused page time and explicitly recorded ChatGPT-assisted time are reported separately.
- A completed assignment is treated as completion evidence; no score is inferred where none was recorded.
- The material index follows the source site's current student-ready resource manifest and release allowlist: 194 distinct files. English review derivatives retain original mathematical typesetting or cell values, with private source hashes and translation mappings. Availability is not evidence of study; materials dated after 21 August 2026 are identified separately. All 738 copied source files remain preserved privately, including superseded and quarantined versions.
