CONTEXT & LIMITS

Know what the demo shows

The app is not a complete HSC course or official education-board service.
It does not provide current official dates, results, or admission requirements.
Notes, answers, and backups are browser-local and are not encrypted.

Use fictional information when trying inputs. The browser edition has no live service, account, payment, dispatch, or external AI integration. Any local saves belong to this browser and device.

COMMON QUESTIONS

Before you explore

Does MyHSCBD include the complete HSC syllabus?

No. It is a study-planning demo with selected notes and practice material.

Are the calendar dates and results official?

No. The app does not provide current board dates or results; its example calendar fixtures are historical.

MATHEMATICAL SPECIFICATION & UNITS

Governing Equations, Inputs, Outputs & Dimensional Conventions

MyHSCBD executes deterministic client-side calculations in the browser. Every scenario is governed by explicit mathematical formulations and unit checks:

Topic Coverage Ratio = (Reviewed Chapters / Selected Module Chapters) × 100; Timed Drill Rate = Questions Completed / Elapsed Minutes

Declared Units & Arithmetic Conventions: Study duration in minutes; practice score in raw correct/total; backup state in validated JSON.

Scope & Operational Boundary: Bilingual selected HSC study notes, questions, timers, plans and JSON backup. Not complete syllabus coverage, official examination dates or result prediction.

REPRODUCIBLE WORKED EXAMPLE & BENCHMARK TABLE

Verified Case Study & Held-Out Reference Table

Worked Verification Case: Bilingual HSC Revision Session: Selecting Physics Paper 1 (Vector & Newtonian Mechanics) or Chemistry Paper 1 notes displays bilingual English/Bangla concept summaries, runs a 15-minute timed MCQ/structured check, logs weak subtopics into the local revision planner, and exports a portable JSON backup.

PROCEDURAL USAGE GUIDE

How to Use MyHSCBD in 3 Reproducible Steps

Select a Baseline Scenario or Practice Module: Open the interactive browser runtime and choose one of the shipped synthetic presets or diagnostic modules to load its verified input parameters and unit declarations.
Inspect Intermediate Traces & Constraints: Review the computed ledger, error diagnostics (MAE/RMSE/margin/balance checks), or bilingual explanations alongside the governing equations documented on mkprep.co.education/methodology/.
Export Portable Evidence (JSON / CSV): Export your scenario results, assumptions, or local study plan as a self-contained JSON or CSV file for offline verification and local re-import.

FREQUENTLY ASKED QUESTIONS

Methodological & Boundary FAQs

Does MyHSCBD include the complete HSC syllabus?

No. It is a study-planning demo with selected notes and practice material.

Are the calendar dates and results official?

No. The app does not provide current board dates or results; its example calendar fixtures are historical.

What mathematical model and units does MyHSCBD use?

MyHSCBD applies Topic Coverage Ratio = (Reviewed Chapters / Selected Module Chapters) × 100; Timed Drill Rate = Questions Completed / Elapsed Minutes. Units: Study duration in minutes; practice score in raw correct/total; backup state in validated JSON.

What are the operational boundaries and limitations of MyHSCBD?

Bilingual selected HSC study notes, questions, timers, plans and JSON backup. Not complete syllabus coverage, official examination dates or result prediction. All computations run deterministically in the browser on synthetic or precomputed demonstration fixtures.

How can I reproduce the benchmark results in MyHSCBD?

Open the interactive browser workspace at ./run/, select Case 1 to inspect the worked result (Bilingual HSC Revision Session: Selecting Physics Paper 1 (Vector & Newtonian Mechanics) or Chemistry Paper 1 notes displays bilingual English/Bangla concept summaries, runs a 15-minute timed MCQ/structured check, logs weak subtopics into the local revision planner, and exports a portable JSON backup.), and export the JSON or CSV evidence ledger.
