DHA Exam Prep Hub

A browser study tool: practice questions, an exam timer, answer feedback and revisiting difficult questions.

Independent study · HTML / JavaScript / localStorage / Local-first

The product problem

Organize short practice sessions and error review without a server installation or account.

Stage

A small browser application is present in source. Material and practice rules need independent updates.

Short practice without an account

An illustrative intended journey, not a demonstration of the current live release.

  1. Open questions in the browser without a server.
  2. Choose practice or a timed attempt.
  3. Review answers and flag difficult questions.
  4. Return to locally stored flags.

System components

  • Practice: answer selection, explanations and correct/incorrect states.
  • Exam mode: timer, attempt completion and a results screen.
  • Flagged questions: localStorage persistence for revisiting difficult topics.
  • Study notes, theme switching and optional sound effects.

Architecture & ownership

One static HTML file contains interface, questions and JavaScript. No separate database or application server is checked in.

How should localStorage and material-freshness limits be explained without promising an exam pass?

What to validate before use

Not an official DHA service or a guarantee of passing. Local data does not synchronize across devices and may be lost when browser data is cleared.

This describes the development scope. This page does not run the product, process payments or verify real-time availability.
