RGSC Study Board

A bilingual (English + Nepali) study and revision website for Nepal's Secondary Level Computer Engineering curriculum — Technical and Vocational stream, Curriculum Development Centre, 2078.

Every topic is explained in simple English first — the exact wording the exam uses — with a Nepali explanation beside it. Both are shown together by default, and a student can switch to Nepali-led or English-only at any time without losing their place. The site is built for students whose English is weak but whose exam is in English.

Status: Grade 10 Data Structure & OOP using C++ and Digital Design & Microprocessor are both complete and live-verified. The other six Grade 9/10 subjects ship their full official syllabus outline. Grades 11–12 are a later phase. See docs/PHASE-3-COMPLETION-REPORT.md for the most recent report.

Works offline, permanently

No build step, no server, no framework, no login, no tracking. Open index.html from a USB stick on a laptop with no internet and the entire site works — simulators, program tracer and quiz included.

The only external request is Google Fonts, and it is optional: every font stack has a local fallback, so the site is fully legible if the request fails.

Run it

Just open index.html in a browser. Nothing to install.

To serve it locally over HTTP instead:

npm run serve

Rebuild it

The published site is generated. Source lives in _source/.

npm run check

That runs npm run build (writes all 28 pages and assets, failing loudly on any content-contract violation) followed by npm test (290 tests covering the build, links, the content contract, the runtime, the storage layer and the design system).

There are no dependencies to install. Node 20+ is the only requirement.

Structure

index.html                 Home — grade picker
grade9/  grade10/          Subject index + one folder per subject
  oop-cpp/                 The complete subject
    unit1…unit6.html         Six lesson pages
    trace.html               Step-through C++ program tracer
    tables.html              Comparison tables + exam terms
    quiz.html                15-question self-check
assets/css  assets/js      One stylesheet, seventeen scripts
_source/                   Source — config, content, design, runtime, build
tests/                     290 automated tests (npm test)
docs/                      Architecture, security, accessibility, decisions

Edit files in _source/, never the generated HTML in the site root — a rebuild overwrites it.

Documentation

Thirty-seven documents, indexed by what you are trying to do: docs/README.md.

The short version — contracts describe how the system works now and must be kept true; phase records are dated accounts of a piece of work and must not be rewritten. Start with docs/ARCHITECTURE.md, then read the contract for whatever you are about to touch.
