What we are working on next
- Audit and transcribe Examples II in both books.
- Confirm all set boundaries and question/subpart counts against scans, including miscellaneous sets.
- Map advanced analytical trigonometry to enrichment units; do not silently omit Part II.
- Maintain worked-example inventory separately from numbered exercise sets.
- Obtain independent mathematical and editorial review before formal assessment release.
