Task #1 Students are always asking for help calculating their final grades at Top Notch Students school. In order to help them out we are going to make a program. We have implemented a policy where the student can get an extra 5% added for perfect attendance and no late assignments, an extra 2.5% if they have 1 or 2 absences or no late assignments. If they have 4 or more absences in a semester then they automatically fail the course. The grading scheme is as follows - 80-100 is an A, 70-80 is a B, 60 - 70 is a C, 50-60 is a D and anything below that is an F. Note that 80 is an A, while 79.99 is a B.
