Canvas Quiz Loader vs ExamGhost: What Happens When You Only Get 1 Attempt?
Canvas Quiz Loader (pfagnepdndhkmilceinbebdfbmiddagl, 50,000 users, 4.1★) is useful on unlimited-retake practice quizzes where the professor reveals every correct answer after Attempt #1. But it contains zero AI: it cannot solve a single question on your first attempt, breaks whenever Canvas randomizes formula variables or pulls from a question bank, and auto-fills answers in 0.2 seconds—leaving an obvious synthetic macro signature in SpeedGrader.
Only copies past Canvas submission HTML—useless on 1-attempt exams
Dev admits changed variables & multi-blank inputs fail to populate

Why 50,000 Students Hit a Wall With Canvas Quiz Loader on Real Exams
Canvas Quiz Loader was built for a single narrow scenario: an unproctored Canvas practice quiz where the professor gives unlimited attempts, never changes the questions, and exposes the full answer key after Attempt #1. Click through the 4 tabs below to see what happens in real college courses.
Requires You to Burn Attempt #1 Before It Can Do Anything
At only 176KiB, Canvas Quiz Loader is a lightweight DOM parser that fetches your /submissions/ HTML history on Canvas. If you have no prior submission—either because it is your first attempt or because it is a single-attempt midterm or final exam—clicking the extension icon returns zero answers.
Solves Attempt #1 Live in 0.3s With Multi-Model STEM Consensus
ExamGhost doesn't wait for you to fail Attempt #1. On your very first attempt, ExamGhost extracts the question context (and any uploaded lecture PDFs in your local Course Materials RAG Vault), routes it through frontier models in parallel, and displays the verified answer inside a subtle Closed Shadow DOM badge.
Fails or Re-Selects Wrong Answers When Professors Hide the Key
Even on multi-attempt quizzes, most professors uncheck “Let Students See The Correct Answers” in Canvas Quiz settings (showing only which questions you missed, or hiding responses entirely until after the due date). When the green .correct_answer DOM class is absent from your previous submission page, Canvas Quiz Loader cannot solve the missed questions—leaving you to guess again or re-filling your old wrong choice.
- ✗ Professor unchecks "Show Correct Answers" → Extension blinded
- ✗ Professor keeps highest vs average score → Attempt #1 hurts GPA
- ✗ Canvas New Quizzes (LTI 1.3 iframe) → Different DOM, scraper breaks
Independent AI Reasoning That Never Relies on Exposed Answer Keys
ExamGhost solves every question from first principles using Multi-Model Consensus + your own course syllabus/slides. Even if your professor completely locks down post-submission review and averages all attempts together, you get the right answer on Attempt #1.
- ✓ Works when post-quiz review is completely locked by instructor
- ✓ Protects GPA when Canvas is set to "Average All Attempts"
- ✓ Native support for both Canvas Classic & Canvas New Quizzes LTI
Breaks on Randomized Formula Numbers & Multi-Blank Questions
In STEM courses (Chemistry, Physics, Calculus, Accounting, Finance), Canvas generates new random variables on every attempt (e.g., Attempt 1 asks for m = 4.2 kg; Attempt 2 asks for m = 7.9 kg). Developer Alex Shnyrov explicitly warns in the store listing:
“* If formula or variables within the formula change, the answer might have to be changed as well.
* Fill in multiple blank question type does not auto-populate.”
Result: Auto-filling Attempt #1's numeric answer into Attempt #2 submits the wrong number and marks the question wrong.
Re-Calculates Every New Variable, LaTeX Formula & Multi-Blank Table
ExamGhost reads the exact live numbers, LaTeX equations, and embedded diagrams on your current screen—re-computing the exact numerical answer to the required decimal places or significant figures on every single question.
- ✓ Solves dynamic Canvas Formula Questions with fresh variables
- ✓ Solves Fill-in-Multiple-Blanks, Matching, & Dropdown matrices
- ✓ ⌘+Shift+S Vision OCR reads chemical structures & physics free-body diagrams
Instant Bulk Auto-Fill Creates Impossible 0.2s Action Logs
When Canvas Quiz Loader “automatically applies them to the current attempt,” its content script loops through every question in the DOM and programmatically sets input.checked = true or dispatches synthetic change events. In Canvas SpeedGrader's Quiz Log, the professor sees 25 questions answered at 00:01 elapsed time with event.isTrusted === false.
Closed Shadow DOM Display + Natural Human Clicks (`isTrusted: true`)
ExamGhost never programmatically mutates Canvas radio inputs or fires bulk auto-fill scripts. Instead, it displays a subtle answer indicator inside an isolated attachShadow({ mode: 'closed' }) container so you click the option yourself at a natural human pace—generating 100% authentic isTrusted: true hardware events while Focus Shield blocks any window.blur logs.
What Your Professor Sees in Canvas SpeedGrader

Extension Name: Canvas Quiz Loader Extension ID: pfagnepdndhkmilceinbebdfbmiddagl Version: 0.5.4 (Updated April 16, 2025) Bundle Size: 176KiB Developer: Alex Shnyrov (1993alexey@gmail.com) Install Base: 50,000 users | 4.1★ (70 ratings) Verbatim Limitations from Store Description: 1. "It scans your previous submissions, picks out correct answers, and automatically applies them to the current attempt." 2. "* If formula or variables within the formula change, the answer might have to be changed as well." 3. "* Fill in multiple blank question type does not auto-populate."
1. Graded First Attempts: In 85%+ of university courses, quizzes either allow a single attempt or average Attempt #1 with Attempt #2. Sacrificing Attempt #1 just to feed an HTML scraper tanks your course average.
2. Randomized Question Banks: When a professor pulls 20 questions from a 100-question Canvas Item Bank, Attempt #2 contains 12–15 brand-new questions that never appeared on Attempt #1.
3. Zero-Second Auto-Fill Fingerprinting: Setting 20+ DOM inputs at the exact same second creates an unmistakable submission timestamp pattern in Canvas SpeedGrader.
“Canvas Quiz Loader worked fine on my freshman syllabus quiz where we got unlimited retakes. Then I tried using it in Organic Chemistry II and Business Finance. First, our midterm only allowed 1 attempt so Quiz Loader literally did nothing. Second, on weekly problem sets where we got 2 attempts, Canvas changed every single number in the formula on Attempt 2—and Quiz Loader pasted my old Attempt 1 numbers right into the boxes and cost me 30%. Switched to ExamGhost and now I get the actual calculated answer on Attempt #1 without burning a single point.”
Canvas Quiz Loader vs ExamGhost: Everything Students Ask
1. Does Canvas Quiz Loader work on your first quiz attempt or single-attempt exams?▼
No. Canvas Quiz Loader (pfagnepdndhkmilceinbebdfbmiddagl, v0.5.4) contains zero AI and cannot solve questions. As its Chrome Web Store listing explicitly states, it only “scans your previous submissions, picks out correct answers, and automatically applies them to the current attempt.” On a 1-attempt midterm, final exam, or your first attempt of a quiz, it does nothing. ExamGhost solves questions live on Attempt #1 in 0.3 seconds.
2. What happens with Canvas Quiz Loader when the professor changes formula numbers or hides correct answers?▼
Developer Alex Shnyrov explicitly warns in the Chrome Web Store description: “If formula or variables within the formula change, the answer might have to be changed as well. Fill in multiple blank question type does not auto-populate.” Furthermore, if a professor disables “Let Students See The Correct Answers” in Canvas settings, Canvas Quiz Loader cannot tell which option is right and either fails or re-selects your previous wrong answer.
3. Can professors detect Canvas Quiz Loader auto-filling answers in SpeedGrader?▼
Yes. Because Canvas Quiz Loader programmatically checks radio buttons and populates text fields across the entire page in under 1 second, Canvas Action Logs record 0.0s–0.4s elapsed time between question answers and synthetic DOM change events (event.isTrusted === false). ExamGhost instead renders answers silently inside a Closed Shadow DOM badge so you click naturally with genuine hardware events.
4. Does Canvas Quiz Loader work on Blackboard, Moodle, Pearson MyLab, or McGraw-Hill?▼
No. Canvas Quiz Loader is hardcoded exclusively for Canvas Classic Quiz submission history tables. ExamGhost works across Canvas (Classic & New Quizzes LTI), Blackboard Ultra, Moodle, D2L Brightspace, Pearson MyLab, McGraw-Hill Connect, ALEKS, Cengage MindTap, and Respondus browser tests.
