Everyone,
Education priorities should add up to 120, increasing the total priorities level above that, does not help. If you are trying to increase graduate numbers, you have to increase the education Index instead.
The correct education index depends on many factors, if your Corps are fully upgraded, the products your Corporations are producing, the balance of State, Private, and Public control of your economy, how large you want your army, and healthcare systems, etc.
As a guide, for a well developed country, an education index of roughly 210, seems to produce a good balance. Your countries will have different ideal levels, but that is a good level overall.
