If you want to display your records in the subform as one record below the other, like an Excel spreadsheet, then set the forms Default View to Datasheet. If you want to change the 'labels' above each column follow the instructions I posted in my previous response. If you are using Continous Forms then you should not have any problems with the labels.
Without more information on your setup between the form and the subform I am going to stick with my suggestion of setting the Master/Child links to GradeLevel or whatever you use to distinguish between grades.
Not a problem with not posting your questions here. When I opened your attachment all I saw were the two questions...
