RoboKET is Lithuania's KET theory test platform that calculates your real probability of passing the Regitra exam — fully available in English. Since 1 January 2026, the Regitra theory exam can be taken in Lithuanian, English, Polish, Spanish and French (Russian was removed). The licence B exam has 30 questions in 30 minutes, and you need at least 80 % correct — a maximum of 6 mistakes. Fewer than half of candidates pass first time. RoboKET trains you for exactly this format, in the language you'll take the exam in. WHAT YOU GET AI INSIGHTS - personalized weekly AI insights - what to do next to pass the exam. PASS PROBABILITY — recalculated after every test; at a stable 90 % it's safe to book your exam. DAILY PLAN — set your exam date and the app spreads your study into 10–20 minutes a day. EXAM MODE — 30 questions / 30 min / 6-mistake limit, no aids, just like at Regitra. QUESTIONS UPDATED TO THE 2026 RULES — with an explanation for every answer. ILLUSTRATED THEORY — short visual cards instead of dry rule texts, fully translated into English. MISTAKE STATISTICS BY TOPIC — see exactly where you're weak and revise with purpose. ALL CATEGORIES — A1, A2, A, B1, B, C, D. ENGLISH AND LITHUANIAN — every question, explanation and theory card in both languages. NO ADS — nothing interrupts your learning. MONEY-BACK GUARANTEE If you reached a 90 % or higher pass probability on the platform but didn't pass the Regitra theory exam on your first attempt — we refund your money. HOW TO START Download and try free KET tests with no registration. When the exam gets close, switch on the full plan and track your probability to 90 %. Perfect for foreigners working or studying in Lithuania who want the licence without fluent Lithuanian.
