Question

Once the course grades have been stored, the page should compute the student's overall GPA. The grade point averages are computed as follows:
1. Grade points (a.k.a. quality points) are assigned to each course based on the grade and number of credit hours:
o A yields 4 points for each hour
o B+ yields 3.5 points for each hour
o B yields 3 points for each hour
o C+ yields 2.5 points for each hour
o C yields 2 points for each hour
o D yields 1 point for each hour
o F, AF, and WF yield 0 points for each hour
2. The grade point average (a.k.a. quality point average) is computed by dividing the total number of grade points earned by the total number of credit hours.
For example, suppose a student entered the following course information (with each line entered in a different dialog box):
THL100 B+ 3
PHL107 A 3
ENG120 C+ 3
MTH245 A 4
CSC221 A 3
