Modern Quiz Builder is the no-nonsense quiz plugin on .org: build a quiz custom post, accept submissions, list results in the admin. The results screen shows one row per attempt with the score, the date and a view link. That UI is fine for spot-checking a single submission. It is poor at answering questions like 'what is the pass rate on the onboarding quiz this month?' or 'which quizzes get the most attempts but the lowest scores?'

SleekView Charts reads the attempts table directly, plus the quiz custom posts the plugin registers. A Number card surfaces total attempts in the last 30 days. A Pie splits attempts across quizzes so the top performers and the dead weight separate cleanly. A Bar groups average score by quiz so a hard quiz stops hiding inside an overall average. An Area trends submissions over time so a Monday launch and a Friday lull show up as shapes, not as rows.

The chart view sits on the same dataset as the table view. Filter to failing attempts only or to the last seven days, and both surfaces narrow together. No exports to Sheets, no manual pivot work, no third-party analytics required.

Modern Quiz Builder is intentionally compact. It registers a quiz custom post, accepts submissions, lists results. That tight scope is its strength and its blind spot.

The plugin writes enough data to answer real teaching questions, but it never surfaces those answers itself. A course can ship with a broken quiz for weeks and the only signal is a row count in a list nobody opens unless someone complains. Charting the same data flips that posture.

A Number card on the admin dashboard catches a drop in attempts on day two, a Pie shows which quizzes carry the course, a Bar of average scores catches the question that nobody is getting right. None of that requires a heavier LMS, just an honest view of the data Modern Quiz Builder is already producing.
