Royal Blue: Average of Red & Green, the Perfect curve                              

Orange: The Great Grading Curve, which approaches the Perfect Curve.


Warning: Never use  y = { x + [ 1 - (x - 1)^2]^.5}/2 or y = x^.56





       Before TGGS, confusion, chaos, fear and despair circled whenever a hard and challenging test was assessed.  With TGGS, peace and tranquility surfaces and caring students are academically inspired and motivated.  To review and correct a test is a very enlightening period of growth for students and the TGGS adjustment is a fitting reward.
