Chem 1062???

If anyone here has taken this course or is currently taking it with Michelle Driesssen and it’s the in person class once a week, I was just wondering if attendance in this class once a week is ever taken or important at all???? Cuz I have people in my round table group that never show up anymore and I keep showing up just in case she takes attendance randomly one day but she never does so is it not part of the grade?
