And if multiple degrees are earned at the same university,
they should be in seperate records. So if you were thinking

[id] [university] [yearStart] [yearEnd] [degreesEarned]
1     U of I       1971        1977      BS MS PhD

you should rethink it as

[id] [university] [yearStart] [yearEnd] [degreeEarned]
1     U of I       1971        1975      BS
1     U of I       1975        1976      MS
1     U of I       1976        1977      PhD
