What it is

A 79-week IGCSE scheme of work for nine subjects, generated from seven official syllabuses rather than copied from a revision site: 185 named units, 1,422 dated blocks, every block tagged with its spec reference, and a build that refuses to finish if a unit was never scheduled.

What broke, and what I’d change

Not written yet. This is the part only I can write — what actually went wrong, and what I’d do differently. It lives in builds/reflections/study-plan-2028.md (see _TEMPLATE.md); as soon as that file has words in it, this section fills in on the next build.

Everything else on this page — the spec, the version history, the file counts — is generated from the project’s own build notes and files, so nothing here is guesswork.

What it is

One offline HTML file that schedules nine IGCSE subjects from 26 Oct 2026 to 30 Apr 2028 (79 weeks, 1,422 blocks) covering 185 official syllabus units, each tagged with the reference it came from.

Hard requirements (do not regress these)

  1. Every unit scheduled. The build prints unscheduled units: none; a unit without a block is a bug,

    2. not a rounding error.

  2. Reference on every block. No block may say only "Chemistry" — it carries 4SD0 Chem 1.1–1.4 or

    3. 0500 P1 Q2(a).

  3. Syllabus version that names 2028. Cambridge codes run in three-year windows (0500 2027–2029,

    4. 0509 2028–2029, 0445 2028–2030, 0457 2028); Pearson keeps one standing Issue (4MA1 Issue 2, 4SD0 Issue 4, 4EC1 Issue 3 Feb 2026). Record which one was read.

  4. Offline. No fetch, no fonts, no CDN. Opens from the Desktop with the network down.
  5. Progress in localStorage (igcse-plan-2028-v1 + igcse-log-2028-v1) with a try/catch fallback so a

    6. blocked store degrades to session-only instead of breaking the page.

Structure

  • 18 slots/week: Mon–Fri 2 blocks, Sat 4, Sun 4.
  • Subjects: Chem 2 · Maths 3 · Phys 2 · Bio 2 · Econ 2 · DT 1 · FLE 2 · CN 2 · GP 1 · Review 1.
  • Phase 1 (W1–30) new unit + two-week-spaced re-touch; Phase 2 (W31–66) same unit as topical past-paper

    • questions marked against the scheme; Phase 3 (W67–79) two subjects a week sit a full timed paper while the rest rework weak topics, then a two-week taper (error log + formula sheets only).

  • Subject queues are reset at each phase boundary — forgetting that makes phase 2 silently continue into the

    • "extra practice" units instead of starting at unit 1.

Regenerating

cd ~/.hermes/scripts/igcse80
python3 prepare_inventories.py     # re-parse /tmp/*.txt syllabus dumps if the PDFs changed
python3 build.py                   # writes ~/Desktop/study-plan-2028-full.html
bash test_plan80.sh                # headless: coverage, DOM counts, checkbox persistence, every tab

Edit units.py (the 185-unit inventory) or build.py (PHASE_A_END / PHASE_B_END / SLOTS / task templates), never the generated HTML.

Checks the test performs

  • PLAN.weeks.length === 79, blocks.length === 1422, 18 blocks in week 1
  • 185 unit tiles, 185 marked "已排", unscheduled === 0
  • ticking a box writes {"w1-0":true} and updates "1 / 18 完成" plus the global counter
  • all five tabs render (coverage / audit / log), audit tables ≥ 9, mistake log saves
  • jumping to a far week re-renders its blocks and phase label

Known limits (stated on the analysis page)

  • Starts at each subject's 1.1; the school's actual position is not known.
  • D&T planned as Paper 3 Materials; Graphic Products changes the option units.
  • 18 blocks ≈ 12 h/week; holidays are labelled but not lightened, no automatic catch-up week.
  • localStorage is per browser, not synced.
