Does Quizgecko grade fixed-answer questions accurately when answers are mixed right and wrong?

Quizgecko graded the mixed fixed-answer attempt correctly. Live question views and the results table distinguished correct from incorrect answers, and the final score matched the row-by-row judgments at 17 of 53 correct, or 32%.

The test case

Each test case is judged on its own: Pass, Fail, Not gradable, or Untested. The scenario result above is based on this test case.

Mixed correct and incorrect fixed answersPassEvidence
What we sent

Input 1: “A: ammeter; V: voltmeter”

Input 2: “A point where the circuit must contain a switch”

Input 3: “The removal creates a break, so a complete loop no longer exists.”

Input 4: “The lamp goes out because the loop is broken at a different point.”

Input 5: “$0.09\,\mathrm{A}$”

Input 6: “The learner will conclude that every component is in series.”

Input 7: “The positions of the components relative to the laboratory bench”

Input 8: “They are drawn beside one another regardless of their electrical connections.”

Input 9: “The lamps are brighter because both receive the full battery potential difference.”

Input 10: “Each parallel lamp receives the full battery potential difference.”

Input 11: “All lamps in one series loop with one switch”

Every message the tool sent, in order (12)
  1. Response to input 1

    Correct | A: ammeter; V: voltmeter

  2. Response to input 2

    Incorrect | A point where wires are electrically joined

  3. Response to input 3

    Correct | The removal creates a break, so a complete loop no longer exists.

  4. Response to input 4

    Correct | The lamp goes out because the loop is broken at a different point.

  5. Response to input 5

    Incorrect | $0.18\,\mathrm{A}$

  6. Response to input 6

    Incorrect | The learner may identify a branch that does not actually exist.

  7. Response to input 7

    Incorrect | The identity and connectivity of every component

  8. Response to input 8

    Incorrect | They are arranged one after another in a single loop with one current path.

  9. Response to input 9

    Incorrect | The lamps are generally dimmer because the supply potential difference is shared.

  10. Response to input 10

    Correct | Each parallel lamp receives the full battery potential difference.

  11. Final response

    Incorrect | All lamps on separate parallel branches with a switch in each branch

Why this result

It is a Pass because the mixed fixed-answer quiz was checked against the key, the product marked right and wrong answers differently, and the final 17/53 score matched those judgments.

Also observed in this test case

Formatting glitch. Several questions render raw LaTeX instead of formatted symbols in the live questions and results table.

Configuration and setup

How this tool was set up for the run and what the test needed in place. Each row is a fact from the run's records; a fact the records do not hold is left out, not guessed.

Set up before the run
An already valid fixed-answer quiz with an answer key and a completed attempt containing both correct and incorrect answers had to be present. The completed attempt was sent through the product's normal grading path.
Grading path
grades each question the moment it's answered rather than waiting for a single end-of-quiz submit

How this scenario is graded

How we decide Pass, Fail and Not gradable. The same rules apply to every tool tested on this scenario.

How results are decided

Each test case gets one result per tool: Pass, Fail or Not gradable. A test case we haven't run yet shows Untested. There are no partial results.

The rules
  • Pass: the tool did everything the test expected, and nothing it said contradicts the correct answer.
  • Fail: at least one expected behaviour clearly didn't happen; the test case's result says which one and quotes the tool.
  • Not gradable: our evidence couldn't settle the outcome (for example a record we needed is missing). It is never counted as a fail, and the test case's result says what's missing.

Where this sits in the benchmark

This page is one cell of a larger study: one tool, one scenario. Only this benchmark's frame appears here.

History of this result

What has happened to this result since it was first published. Runs and grades are never overwritten: a retest or a re-grade publishes a new result and keeps the earlier one readable.

Act on this result

Nothing filed here edits the run or the grade. A challenge opens a review, and a review can produce a new run or a re-grade — which becomes the current result and leaves this one in the history.

This matches what I see

You run the same kind of test against your own setup and get the same behaviour.
