What Grade? is a grade calculator for students, parents, and teachers to use to estimate the performance needed for the remainder of the semester and year to achieve a letter-grade goal.
It is offered as a plain vanilla script that you can include in your website and style as you wish.
You can modify the grading scale to match that of your school system. Edit the script, find the section where the grading scale is defined, and modify it there.
The default grading scale is A+ (97), A (93), A- (90), B+ (87), B (83), B- (80), C+ (77), C (73), C- (70), D+ (67), and D (65), with F at 65.
For your convenience two other grading scales can be found in the script, commented out: 1) A+ (97), A (90), B+ (86), B (80), C+ (76), C (70), D+ (66), and D (60), with F at 60, and 2) A (90), B (80), C (70), D (60), with F at 60.
