Does PDF to Quiz tailor practice to earlier weaknesses when a learner returns?

PDF to Quiz retained the learner’s history across sessions but did not use it to target weaker topics. Practice restarted the fixed 47-question quiz with a previously answered fuse question from the learner’s stronger area, rather than focusing on parallel circuits.

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.

Expected vs. Found
✗Expected: Each learner’s new-session practice must use retained history to target their own weaker topic, rather than serving the same fixed focus.Found: It retained 53% mastery from one attempt, then served question 1 of the full 47-question quiz: a previously answered fuse item from the learner’s stronger area.

Why this result

History survived, but practice had to respond to earlier weaknesses. One learner returned; the absence of personalization controls meant a second learner could not receive a different focus. The failure concerns the practice offered to this account.

Also observed in this test case

Weaknesses are visible. The quiz page’s lists of top correct and incorrect answers make the learner’s weak areas visible.

Pro feedback is not targeting. The website describes the Pro plan’s personalized breakdown as feedback after a quiz; choosing the next session’s questions remains with the learner.

Set up before the run
One learner completed a 47-question electric-circuits quiz (53% mastery), signed out and back in, then opened practice. A second learner with opposite weaknesses was not tested: practice offered no topic or weak-area control.

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
