should studentts get saturday school when there late ?

I feel that students should not get Saturday school when there late because half of the teachers are late to school almost every day . Second of all I feel that its not fair that we as students should have to cancel are passes to see are family to go to Saturday school . from my prospective I feel that when teachers are late they should be marked down tarty to . For an example Ms. Priester is late to school almost every day of the week . because of that I feel that the teachers that are late should be going to Saturday school as the  teacher that is teaching.
