LRNRS Battle Mode is a free live quiz battle platform for college instructors and professional exam prep programs. Instructors launch real-time competitive quizzes in under 60 seconds — no student accounts required. Students join with a 4-digit code from any device. Unlike Kahoot, LRNRS is built for serious academic content: full LaTeX equation rendering for STEM courses, NCLEX-style clinical scenarios for nursing programs, and AI-generated question packs. Supports individual battles, relay teams, and async campaign mode for homework-style battles. Free tier includes unlimited battles with up to 10 questions. Paid Creator tier ($9.99/mo) unlocks 40 questions, AI credits, and CSV import.
