Notes:
1.  The average semester GPA underestimates the average of
the grades awarded, since students who do worse in school tend
tend to take fewer classes.  Based on 1950s data, the semester GPA
is about 0.10 lower than the average of all grades awarded to students.
So, to estimate the average grade awarded during the above time periods,
you may want to add approximately 0.10.
2.  Before 1955, Penn State's grading system was on a -2 to 3 scale.
I have added 1 to the original GPA's to obtain a common 4.0 scale.
