There should not be any issues with completing Smart Tuition grade mapping for next year, as the grades are linked directly to each other and not necessarily to the School Level. As long as the order of grades isn't changing, grades are not being removed, and they are set up the same way in Smart for the coming year, contracts and mapping information should be fine as is.

Grade Level Mapping can be found under Core> Settings> Smart Tuition> Grade Mapping.
