GPA Calculation Suite Four Oh!

This suite of tools is intended for both instructors and students to assess various dimensions of their GPA based on current values, in order to predict future outcomes.
This suite consists of three tools:
Tool 1 - Potential semester GPA Estimator is intended to track your current semester based on your estimated grades.
Tool 2 - Cumulative GPA estimator is intended to combine your estimated GPA and course hours for your current semester with your overall GPA to determine your projected cumulative GPA
Tool 3 - Required GPA for a target considers your current cumulative GPA and course hours, and your target GPA required (e.g., for a degree program) and estimates your required semester GPA to fulfill this requirement

All values carry over between tools, for simplicity!
