CONTEXT & LIMITS

Know what the demo shows

This is not an ETS product or a full adaptive GRE exam.
Practice results are local evidence, not official scaled scores or score predictions.
The question bank is limited, and repeated questions can affect accuracy.

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 MyGREBD predict my official GRE score?

No. It reports local practice results and makes no official score estimate.

Are these official GRE questions?

MATHEMATICAL SPECIFICATION & UNITS

Governing Equations, Inputs, Outputs & Dimensional Conventions

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

Local Practice Accuracy (%) = (Correct Responses / Attempted Items) × 100; Spaced Review Interval I_k = I_{k−1} × Ease_Factor (bounded to local browser study calendar)

Declared Units & Arithmetic Conventions: Practice accuracy in %; response latency in seconds/item; vocabulary review intervals in days; weekly study targets in minutes/week.

Scope & Operational Boundary: Original GRE-style bilingual practice, timed sets, vocabulary scheduling and plans. Limited original practice bank; no ETS affiliation, adaptive test or score prediction.

PROCEDURAL USAGE GUIDE

How to Use MyGREBD 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.

FREQUENTLY ASKED QUESTIONS

Methodological & Boundary FAQs

Does MyGREBD predict my official GRE score?

No. It reports local practice results and makes no official score estimate.

Are these official GRE questions?

No. The practice set is an independent, limited learning bank.

What mathematical model and units does MyGREBD use?

MyGREBD applies Local Practice Accuracy (%) = (Correct Responses / Attempted Items) × 100; Spaced Review Interval I_k = I_{k−1} × Ease_Factor (bounded to local browser study calendar). Units: Practice accuracy in %; response latency in seconds/item; vocabulary review intervals in days; weekly study targets in minutes/week.

What are the operational boundaries and limitations of MyGREBD?

Original GRE-style bilingual practice, timed sets, vocabulary scheduling and plans. Limited original practice bank; no ETS affiliation, adaptive test or score prediction. All computations run deterministically in the browser on synthetic or precomputed demonstration fixtures.

How can I reproduce the benchmark results in MyGREBD?

Open the interactive browser workspace at ./run/, select Case 1 to inspect the worked result (Diagnostic Set Walkthrough: Completing a 10-item mixed Verbal (Text Completion / Reading Comprehension) and Quantitative Reasoning drill records per-item timing and bilingual (English/Bangla) error rationales locally in localStorage, scheduling missed GRE vocabulary roots for 1-day, 3-day, and 7-day spaced repetition without generating an official ETS scaled (130–170) score prediction.), and export the JSON or CSV evidence ledger.
