Case Ace

Roleplays, PI study, exam prep, and written event feedback — one workspace built only for DECA.

Free to start. No credit card required.

Roleplay Practice

Run an official-style roleplay whenever you want

Pick your career cluster and event, and Case Ace generates a case built on real competition performance indicators. Present it out loud with your webcam and mic, then get scored the way a DECA judge scores you — PI by PI, on the official 100-point structure.

  • Cases built from official performance indicators
  • Every DECA event across all six career clusters
  • Upload a real case from practice and run that instead

Study PIs

14,500+ flashcards with explanations that actually teach

Every performance indicator across every event, as flashcards or quiz mode. Flip a card and you don't just get the definition — you get an explanation with a concrete business example, so the PI makes sense when a judge asks about it.

  • Filter by career cluster or specific event
  • AI explanations with real-world examples
  • Track what you know well and what needs review

Exam Practice

Train for the 100-question exam the way it's actually given

Warm up with 10-question practice sets, then sit the full 100-question, 90-minute simulation when you're ready. Wrong answers go into a review pile so you drill what you missed, and XP, levels, and streaks keep you coming back.

  • Practice, full exam, and speed round modes
  • Per-event question banks with instant or end-of-exam feedback
  • Review mistakes, exam history, and a leaderboard

Written Events

Judge-style feedback on your written entry

Paste a draft of your executive summary or full written event and get rubric-based feedback in minutes — what's strong, what's thin, and what a judge will flag. Revise, resubmit, repeat until it holds up.

  • Evaluated against the official DECA rubric
  • Works for every written event type
  • Section-by-section notes, not vague praise
