Being able to focus on three subjects at a time allows students to fully invest in their learning in those particular subjects. In addition, they are being well prepared for college academics, as many colleges and universities operate on semester schedules. Especially important to note is the student-to-teacher ratio. As most teachers work with only 30 students in the academic setting (average of 13 students per class), they are able to give each student one-on-one attention in and out of the classroom.
