Everyday Learning with OSSD

OSSD recognizes the difficulty in online learning for high school students. We developed our curriculum online on user-friendly Canvas and divided the curriculum into everyday tasks for students to easily follow. On average, you will study for six (6) hours a day, supported by your teachers whom you can reach via email and live classrooms. To ensure that the student takes responsibility for their study, we combined online education with 60% self-study and 40% live course so that the student can interact with the teachers, who then check the student’s work.
