From quick drills to full-length tests, AI coaching to real-time analytics — every tool engineered for maximum score improvement.
Ten integrated tools that work together to accelerate your progress.
Quick Practice sessions are powered by our adaptive algorithm. Each question is selected to maximize information gain on your weakest skill vectors. Whether you have 5 minutes or 50, every second counts.
The AI Coach understands your skill profile and adapts to your learning style. Ask it to find specific question types, generate custom drills for tricky topics, explain complex grammar rules, or even adjust your algorithm parameters — all through natural conversation.
Our tracker decomposes your exam into 13 independent skill vectors and updates them after every single answer. Strengths become clear. Weaknesses become targets. The algorithm uses this data to automatically prioritize what matters most.
Track practice frequency, accuracy trends, time-per-question patterns, and projected scores. See which sessions were most productive, identify your peak study hours, and understand exactly how each drill contributes to your progress.
Organize your practice by exam section, topic, or skill area. Each workbook chapter builds progressively — from concept review to targeted drills to assessment. Perfect for systematic, deep study sessions.
Over 30 complete practice tests that replicate real exam conditions. Full timing, authentic question formats, and scoring algorithms calibrated to match official scales. Know exactly where you stand before test day.
Our mobile application gives you the full LangArena experience in your pocket. Set daily goals, track streaks, and monitor your progress trajectory — all synced in real time across every device.
