DHA Exam Prep Hub · Build dossier

What the code says

• The 664-question bank is held inline in the file as objects with id, question, options, correct, block and difficulty fields

  Source index.html

• By difficulty: 284 hard, 243 medium and 137 easy, summing to the full bank size

  Source index.html

• 26 topic blocks; the largest: product knowledge 128, procedures 92, regulations 75, anatomy 61

  Source index.html

• A trial draws 50 shuffled questions, and the options are re-shuffled with the correct-answer index recomputed

  Source index.html

• Progress and flagged questions persist in localStorage under keys prefixed with dha_

  Source index.html

• One inline script, and the only outbound links are the regulator address and a return to moonsugar.space; the source pulls its font from a third-party CDN while the published build serves it locally

Module state

1. implemented

   The question bank and trial delivery

   664 questions are served with option shuffling, and a trial draws 50 from the pool.

   Source index.html

2. implemented

   Answer checking and a filter for malformed items

   The correct answer is matched against the options array; normalizeQuestion and validateQuestion drop items whose answer is not among the options, logging to the console.

   Source index.html

3. implemented

   Offline state

   The progress screen and the flagged-question list live in localStorage under dha_ keys.

   Source index.html

4. partial

   The timer and the modes

   Timer code and a 50-question draw exist, but distinct modes such as flashcards or a labelled mock exam were not found in the file.

   Source index.html

5. not implemented

   Build, tests and CI

   The hub has no build pipeline, test files or workflow: under .github only an instructions file exists, and regressions are not blocked.

6. on roadmap

   Aligning the bank with the current syllabus

   Keeping the 664 questions aligned with the current licensing programme is manual work; the file has no automated reconciliation with the regulator source.

   Source README.md

How this was checked

• The 664 count is verifiable by counting bank entries

  The file holds 664 objects of the id-plus-question shape, and the blocks and difficulty counts sum to the same 664.

  Source index.html

• The difficulty split accounts for the whole bank

  284 hard, 243 medium and 137 easy add up to exactly 664.

  Source index.html

• The published page loads nothing from outside itself

  In the built artifact the font reference is rewritten to a local path, and no link, script or img tag carrying an http address exists in the source or the build.

  Source index.html

Limits of these claims

• The questions are author-prepared; this is not the official regulator exam and does not guarantee alignment with the current syllabus.
• No verification against the current licensing programme is documented in the repository.
• No build, tests or CI: the file is edited by hand and behavioural regressions are not blocked.
• Beyond practice and progress, no further modes such as flashcards or a labelled mock exam were found in the file.
• State is local only: progress does not sync across devices and is lost when localStorage is cleared.
• The question content is English; no separate RU or AR localisation layer was found inside the app.

Build directory

.

The subdomain serves exactly that one file from the repository: the 664-question bank is inlined, nothing reaches out to third parties and the font is served locally, so once loaded the page keeps working offline. It is independent practice, not an official DHA trainer, and flagged questions stay in the browser only.

The page itself does not confirm availability: the host is checked when the build is published.
