Overall score: 2 / 3
You earned full credit on algorithm structure and readability. One rubric row needs evidence tying Big-O to your code.
Based on your rubric gaps, we suggest one practice pack with warm-ups, several multiple-choice drills on your weak row, and a checklist.
This is not a single question. Each pack includes targeted items (e.g. tying Big-O to loops, nesting, recursion, and halving steps), then a checklist you can revisit in the same session before you refresh.
You’re in the middle third of this class (anonymous).
Survey mode: practice progress is kept only for this visit. Refreshing or reopening the page starts clean so each participant sees the same baseline.
Tap a row for details. Rows with gaps open a pack with warm-ups, several gap-specific questions, and a checklist.
Highlight 1
State and Example are short warm-ups (not scored quiz items). Only the Match multiple-choice steps count as practice questions, then the checklist. During this visit you can move around the app and come back; refreshing or closing the tab clears progress (survey prototype).
There are no rubric rows where you lost points that still need a finished practice pack—or you’ve already completed them all. You don’t need the checklist or another rubric item for today.
Congratulations
This assignment has no other rubric rows where you lost points—finishing this checklist covers every gap. Save progress below, then you can return to the overview.
Track suggested practice packs tied to rubric gaps. Each pack includes warm-ups, several gap-targeted questions, and a checklist. Nothing is stored after refresh.
Optional: Add reminder to calendar (not wired in prototype).
