The CS course,
rebuilt for 2026.
Hand out plagiarism-resistant assignments. Watch 100+ students trace algorithms in real time. Stop competing with ChatGPT, teach with it.
Already piloting with Prof. Michael Wehar at Bryn Mawr College (11 students, Jan–May 2026). Bryn Mawr purchased Ultimate for the class for one year. Free for educators during the pilot.
Your students aren't the ones falling behind.
The problem isn't motivation. It's that your course tooling was built before AI could one-shot a sorting algorithm.
The 2008 playbook
- ✕Identical problem sets graded weeks late
- ✕No visibility until the midterm reveals the gap
- ✕Assignments solvable by any LLM in 3 seconds
- ✕Nothing engaging to compete with TikTok at 11pm
The AlgoArena playbook
- Randomized, auto-graded problems unique per student
- Live dashboard, see who's stuck before they give up
- AI-fluency scoring, reward using AI well, not hiding it
- 1v1 battles and puzzle rush make practice addictive
Show the real classroom flow. The host starts a quiz, the MCQ appears, answers come in, and the leaderboard updates.
- Start with the host view so the context is obvious.
- Show one MCQ question with a timer, then jump to leaderboard movement.
- Keep it crisp. One question, one scoreboard change, done.
- If possible, capture 10–20 participants so it feels real (or duplicate clients).
Once you record, we’ll swap `videoSrc` in and this block becomes a real product artifact.
Kahoot,
but for algorithms.
Start a live session, broadcast a problem, watch the class solve in real time on a leaderboard. Office hours, recitations, and exam review become the part students show up early for.
Host a SessionEvery student
gets their own problem.
10,000+ problems across arrays, graphs, DP, and more, auto-selected per student by topic and difficulty. Copy-pasting a classmate's answer just doesn't work. Neither does pasting ChatGPT's: we also measure how they got there.

Already in the classroom.
Professor Michael Wehar at Bryn Mawr College is running an “Algorithms for Competitive Programming” course powered by AlgoArena. Students practice on the platform, compete on leaderboards, and prepare for class tournaments, solving the three biggest pain points in CS education:
Finding quality practice problems for students
Offering programming practice outside the classroom
Helping students prepare for technical interviews
Grant funding pending for expanded deployment. Interested in a pilot at your institution?
Free during the pilot.
We're working with a small cohort of CS instructors to make Classroom the best way to run a modern CS course. While we do, it's on us. No card, no seat caps, no nonsense.
See pricing detailsQuestions educators actually ask
How long does it take to set up a class?
About 15 minutes. Create an educator account, import a roster (or let students join by code), assign a problem set. You can run a live classroom session the same afternoon.
What about academic integrity with AI tools?
We don't fight AI use, we measure it. Assessments capture prompt quality, iteration patterns, and debugging behavior. Students who use AI well get credit for using it well. Students who copy-paste without understanding are visible.
Do students need to pay?
Not for anything you assign. Students who want the premium consumer features (extra AI tutoring, tournaments) can upgrade on their own, but classroom work is covered under your pilot.
Will this work with my LMS?
Roster import today, grade export to CSV. Deeper LMS integration (Canvas, Blackboard) is on the roadmap, tell us what you use and we'll prioritize it in the pilot.
What's the institutional pricing going to be?
We're figuring it out with the pilot cohort. It'll be per-seat or per-department, and we'll grandfather pilot institutions into whatever we land on.
Your syllabus, upgraded.
Tell us what you teach and who you teach it to. We'll get you set up in your next office hours block.
