Evolving, simple TGGS  formulas emerge from y = x ^ s where x is a percent score and s is a test difficulty index with  0 < s <= 1.

This TGGS website is not about inflating grades!  When students require test modifications, TGGS offers reasonable options without redefining each test; simply, choose the appropriate grading curve for the individual learner with specific needs.
