CONTEXT & LIMITS

Know what the demo shows

This is not an ETS product or a full adaptive TOEFL simulation.
Speaking and open writing are not automatically graded; practice does not produce an official score.
Registration guidance may be outdated, and recordings or backups remain under your browser's control.

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.

MATHEMATICAL SPECIFICATION & UNITS

Governing Equations, Inputs, Outputs & Dimensional Conventions

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

Section Pacing Rate = Words_or_Items / Allowed_Minutes; Self-Rubric Score = Σ_{d=1..4} Rubric_Dimension_d / 4 (0–4 scale)

Declared Units & Arithmetic Conventions: Reading/Listening practice accuracy in %; Speaking response timer in seconds (15 s prep / 45 s response); Writing word count and self-check rubric.

Scope & Operational Boundary: TOEFL-style practice, local writing and speaking records, objectives and study plans. No ETS affiliation, official registration or automated speaking/writing scoring.

REPRODUCIBLE WORKED EXAMPLE & BENCHMARK TABLE

Verified Case Study & Held-Out Reference Table

Worked Verification Case: Academic Integrated Task Walkthrough: Learners complete an independent reading/listening passage check, record a local 45-second speaking outline or 250-word academic discussion response in the browser, grade it against a transparent 4-point structural checklist (claim, textual evidence, cohesion, grammar), and save their study plan locally without any ETS affiliation or automated AI score prediction.

PROCEDURAL USAGE GUIDE

How to Use mytoeflbd 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 khaniq.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.
