You will be marked late if you come in late, regardless of whether or not you get a late pass. You can see your attendance information on your eschooldata account, under Attendance. You will not be officially marked late to school if you come in to school on time but show up late to class. However, your teacher may mark you late, which could adversely impact your grade. Showing up late to school doesn't impact you directly. It only matters if your teacher marks you down because you're late to that class.
