Can PDF to Quiz grade mixed correct and incorrect fixed answers?

PDF to Quiz passes this mixed-answer grading case. Live marking, the review cards, and the final tally show correct answers marked green and wrong answers marked red, ending at 7 correct, 7 incorrect, and 50%.

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.

What the tool returned

50% Good effort! Review the incorrect answers below to improve. 7 Correct 7 Incorrect Correct Answer: 0.90 A (green bar). Your Answer: 0.90 A (green bar). Explanation: Branch currents in a parallel connection recombine in the return path, so the total current is the algebraic sum of the branch currents: 0.50 A + 0.40 A = 0.90 A. Reading 0.40 A or 0.50 A would report only one branch's contribution, not the combined flow. 0.10 A is the difference of the branch currents and is not the total returning current. Which procedure reliably identifies that a set of components are connected in series? Correct Answer: Trace from one terminal of the battery and confirm there is exactly one route back to the other terminal (green bar). Your Answer: Check that each component has its own separate path to the battery terminals (red bar). Explanation: Series connection means a single path passes sequentially through the components; tracing one terminal back to the other by only one route confirms series.

Why this result

The attempt was to be graded against the key. The live marks, review cards, and final tally show correct and incorrect answers separated properly, and the final tally matches them at 7 correct, 7 incorrect, and 50%.

Also observed in this test case

Order changes. Question and option order changes between attempts, so answers must be matched by question text rather than position.

Live marking. Each selection is marked immediately in Study Mode during the retake, showing live grading rather than delayed marking.

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.

Something here is wrong — a reference value, a transcription, a grade.
