A question about group structure?

hi, all

I have one report like this:

Students Scores For Class 1
StudentID StudentName Age Score........
.......
Average:.......

Students Scores For Class 2
StudentID StudentName Age Score........
.......
Average:.......
...

For this report, I need to show StudentID StudentName...... on every page as header, but Students Scores For Class only show once for each class.
So, in this case, the structure would be:
GroupHeader --> Students Scores For Class 2
--> StudentID StudentName Age Score........
TableDetail .......
GroupFooter -- >Average:.......
What would the StudentID, StudentName..... be in order to show it on each page Do I need to create one more group
Thanks.
