What is the advantage of joining Ut from std. IX onwards?

In order to excel in the board exams, students need to have an indepth knowledge and strong conceptual understanding in the major subjects from std. IX onwards.

False, as a matter of a fact our teachers spend probably slightly greater number of hours that recommended by the ICSE Board. It is felt this way primarily because our lectures are more efficient.
