A Useful JavaScript Program

Many web pages make use of JavaScript (and Java too) for relatively useless purposes such as image rollovers, animations, watermarks, and automatic scrolling. I wanted to learn JavaScript, and in the process, create something that would be useful.

I created a grade calculator for my students to use. The calculator starts by presenting a form for students to enter their scores. When complete, a JavaScript program takes over and computes the student's standing. It also makes projections.

The illustration below shows screen shots of the input for and the output. If you'd like to use the calculator and view the source, the link is here.
