This fall I start classes, but do anticipate missing a week of classes. I am attending part-time (3 classes), which means I would miss a total of 6 classes, two on monday, two on tuesday, and two on thursday. Of the entire semester, these will be the only classes missed. Will this have a major affect on my grades? I have the opportunity to study 40 hours a week, because my full-time job allows me to study.
