    The GradeMatic 3000 is the third in CI's line of calculators for teachers, following the 100 and 200, and preceding the 4000.  (Why did they inflate the model numbers by 10?  Good question.)  It accepts student grades as input and calculates grades based on standard or self-designed grade scales.  This model deleted the timer present on the earlier models--it returned on the 4000.
