CONTEXT & LIMITS

Know what the demo shows

The lesson collection is small and does not cover advanced B2–C2 study.
It does not provide an official credential, AI assessment, or microphone recording.
Directory and planning examples are not live or verified; local data may not persist on every browser.

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 MyFrenchBD assess my French level?

No. Its short orientation is not a calibrated proficiency test or official assessment.

Can I use it to verify French courses or France requirements?

No. The discovery and planning records are demo examples and should not be treated as current guidance.

MATHEMATICAL SPECIFICATION & UNITS

Governing Equations, Inputs, Outputs & Dimensional Conventions

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

Lesson Completion Progress = Σ_{i=1..6} Completed_Lesson_i / 6; Spaced Recall Score = Correct Prompts / Total Prompts in Lesson Set

Declared Units & Arithmetic Conventions: 6 structured sample lessons spanning introductory A1–B1 communicative patterns; local learning passport stored in browser JSON.

Scope & Operational Boundary: Six A1–B1 sample lessons, practice activities and a local learning passport. Not a full CEFR curriculum, calibrated assessment or visa-advice service.

REPRODUCIBLE WORKED EXAMPLE & BENCHMARK TABLE

Verified Case Study & Held-Out Reference Table

Worked Verification Case: Sample Lesson Contrast (A1 Present vs. Near Future — 'aller + infinitive'): Compares French sentence structure ('Je vais étudier ce soir') with English ('I am going to study tonight') and Bangla ('আমি আজ রাতে পড়তে যাচ্ছি'), followed by an interactive fill-in-the-blank check and local passport checkpoint.

PROCEDURAL USAGE GUIDE

How to Use MyFrenchBD 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 mkstudy.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 MyFrenchBD assess my French level?

No. Its short orientation is not a calibrated proficiency test or official assessment.

Can I use it to verify French courses or France requirements?

No. The discovery and planning records are demo examples and should not be treated as current guidance.

What mathematical model and units does MyFrenchBD use?

MyFrenchBD applies Lesson Completion Progress = Σ_{i=1..6} Completed_Lesson_i / 6; Spaced Recall Score = Correct Prompts / Total Prompts in Lesson Set. Units: 6 structured sample lessons spanning introductory A1–B1 communicative patterns; local learning passport stored in browser JSON.

What are the operational boundaries and limitations of MyFrenchBD?

Six A1–B1 sample lessons, practice activities and a local learning passport. Not a full CEFR curriculum, calibrated assessment or visa-advice service. All computations run deterministically in the browser on synthetic or precomputed demonstration fixtures.

How can I reproduce the benchmark results in MyFrenchBD?

Open the interactive browser workspace at ./run/, select Case 1 to inspect the worked result (Sample Lesson Contrast (A1 Present vs. Near Future — 'aller + infinitive'): Compares French sentence structure ('Je vais étudier ce soir') with English ('I am going to study tonight') and Bangla ('আমি আজ রাতে পড়তে যাচ্ছি'), followed by an interactive fill-in-the-blank check and local passport checkpoint.), and export the JSON or CSV evidence ledger.
