SAT Question Bank Tracker

A Chrome extension that tracks your progress on satquestionbank.org. For every question you answer it records:

• the question id (from the URL, e.g. 3b6b5f30),
• the category / skill (e.g. Algebra – Linear equations in one variable),
• the difficulty (Easy / Medium / Hard),
• whether you got it right on your first try,
• and a link back to the question so you can review it later.

A side panel then shows where you're strong and weak — first-try accuracy by skill (weakest first). Each skill row is an aggregate you can tap to expand into its Easy / Medium / Hard sub-stats (e.g. Linear equations in one variable breaks into easy, medium, and hard), plus an overall by-difficulty rollup. Each difficulty lists clickable review links to the individual questions — color-coded (green = first-try correct, red = first-try wrong) and ordered wrong-first — so you can jump straight back to anything you missed. All data is stored locally in the extension (chrome.storage.local); nothing is sent anywhere.

Install (load unpacked)

1. Open chrome://extensions.
2. Turn on Developer mode (top-right).
3. Click Load unpacked and select this sqbtracker/ folder.
4. Pin the extension and click its toolbar icon to open the side panel.

Use

1. Open any question, e.g. https://satquestionbank.org/question/<id>?set=<set>.
2. Pick an answer and click Submit. The extension detects the result automatically.
3. Click the toolbar icon to open the side panel and watch your stats update live.
   • Clicking Next between questions works without reloading — the tracker follows the site's in-page navigation.

Only the first attempt at each question id counts toward your first-try accuracy. Re-answering a question later won't change that question's first-try result (but is still counted in its attempt total).

Buttons

• Export — download all tracked data as JSON (backup / move to another machine).
• Import — merge a previously exported JSON file (existing first-try results are kept).
• Reset — delete all tracked progress.

How it works

The site is a client-side app that grades answers in the browser: when you submit, the chosen answer turns green (correct) or red (incorrect). The content script (src/content.js) reads that reveal from the page, scrapes the category (<h2>) and difficulty (title="Question Difficulty: …"), and saves the result via the shared storage layer (src/storage.js). The side panel (src/sidepanel.js) aggregates and displays it.

Notes

• Detection relies on the site's green/red result styling and a few selectors. If the site is significantly redesigned, the selectors in src/content.js (readResult, findCategory, findDifficulty) are the only things that should need updating.
• Data lives in chrome.storage.local (not sync) so a large history won't hit sync quotas; use Export/Import to move data between machines.
