So could the former because where I'm from there's a certain amount of times you can not be in a class (without a doctor's note that justifies it) before you face expulsion. IIRC that number is around 20 classes per school year, so that alone brought me to 1/20th of an expulsion.

And being the teen that I was, it's not like I had an otherwise perfect attendance in any of my high school years.
