Does Studyglen accurately grade a learner’s mix of correct and incorrect fixed answers?
Studyglen correctly graded the learner’s mix of correct and incorrect fixed answers. It reported 10 correct and 10 incorrect answers, giving 50% for 10 correct out of 20.

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
We submitted the completed Series and Parallel Circuits quiz through the Submit quiz button, with all 20 questions answered.
The tool's response has no text to quote: it is what the evidence under Proofs shows.
| ✓ | Expected: Judge each response against the correct answer key, distinguish correct from incorrect responses accurately, and calculate an attempt total consistent with those judgments.Found: Questions 5 and 6 were marked correct; questions 8 and 20 were marked incorrect. The total was 50%: 10 correct out of 20, with 10 incorrect. |
Studyglen graded the whole completed attempt submitted through the learner interface. Its marks agree with the source chapter, not just its own answer key, and its percentage follows from the correct-answer count. This meets the requirement for accurate per-question grading and a consistent total.
Similar-looking answer choices. Question 8’s first and fourth options look similar but mean different things. The weakness is in answer-choice wording, not grading.
Explanations linked to source material. Every marked question includes an explanation and a reference to its source document, allowing the learner to trace the grading back to the material.
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.
How this scenario is graded
How we decide Pass, Fail and Not gradable. The same rules apply to every tool tested on this scenario.
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.
- 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.

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.
You run the same kind of test against your own setup and get the same behaviour.
Agree →Yours behaves differently. Tell us what you got, with a screenshot if you have one.
Disagree →Something here is wrong — a reference value, a transcription, a grade.
Report an issue →Tell us what changed and we schedule a rerun of the failing test case. The old result stays as history.
Vendor notice →The same record is available as structured data through the AI Demos MCP server, with the counts, the coverage and every per-test-case reason carried as fields.
