VIII is a point to move from customary tuition teacher to full fledged coaching classes. And there is good point behind it. From std.

There is a need for teachers who are expert in their respective subjects. Then only proper justice can be done to all the subjects. It is a time to introduce students to newer concepts like weekly test and surprise tests etc.
