"The UBT Exam Simulation Platform was developed for a Korean language class teacher, Dilahn Kaushalya, to digitally replicate the structure, difficulty, and experience of the official Korean UBT examination. The system allows students to practice exams in a realistic environment while enabling the teacher to manage exams, students, payments, and performance analytics through a powerful admin dashboard."

Project Background
Preparing students for the Korean UBT exam requires not only subject knowledge but also familiarity with the exam environment and pressure. Traditional paper-based or basic online tests fail to replicate real exam conditions. This platform was designed to provide a secure, interruption-tolerant, and highly realistic exam experience while giving the teacher full control over exams, students, and performance insights.
