KeyOn English is an application that supports students to take the English high school graduation exam. The application consists of three parts:
1. Test practice: includes all the real exam simulations, and the most effective preparation for exams such as creating the test based on competency, explaining the answers in detail and retraining the question selectively
2. Account management section: includes registration and level tracking, and suggests individual focus knowledge for each learner
3. Communication and sharing: to assist English teachers in managing their own classrooms, and will supplement topic-test sharing between students / teachers

The KeyOn English app is free for all to use, and the members who build this app really want students to overcome themselves and receive benefits. Finally, students improve their scores on the high school graduation exam, which nearly every student takes only once in their lifetime.
