Last week of school

As the days of the fall 2007 semester comes to an end i notice many people who have not studied at all are trying to cram a semesters worth of class into one week. For example, in my calculas i have studied every single day for at least an hour and ive got an A yet the guys next to me have not passed one test and assume that if they cram everything in one week they will get an A on the final and pass the class with a C. Well to them i say good luck but i have a lot of doubt.
