Dagao was a quiz platform developed to help students in Bangladesh prepare for university admission tests. The platform offered a comprehensive question bank with multiple-choice questions (MCQs) and provided students with tools to practice, compete, and track their progress. One key feature was real time PvP mode where students could select a subject and get matched with other students to compete on same set of questions and rise the leaderboard.
